I’ve promised to share with my El Camino project details every Tuesday morning, so let’s start by reviewing the factory installed options it came with. To help guide us through the process, I’ve pulled up the ’87 El Camino options page for the base model. The blue boxes indicate available options, and the green boxes indicate the features on my truck (reviewed in the following section).
First up is the four speed overdrive automatic. Although it is a base truck with the base motor, the presence of a transmission upgrade gives us the promise of better things, and as we’ll see there’s other nice features on board.
Such as factory air conditioning. While I possess the skills necessary to add factory air to any car, it’s not a project I’d take on casually. The under-hood parts pretty much bolt up, but the under-dash air box and ducting requires complete dash removal, and may require a new dash skin with additional face ducts in the center. Therefore, getting AC from the factory is a big score.
Next is the gage package with trip odometer. In GM speak, “gage” refers to the dash gauges. Early 5th generation base cars used a ribbon speedometer with a serious sixties look (Top image). Along the way, they replaced the ribbon speedometer with a round speedometer, fuel gauge and “idiot lights” (Lower image).
Thank the Lord, my car shipped with this gauge option, putting a couple of orange pointers in the gauge cluster. However, there is still a blanking plate in the tach opening, reminding me the buyer cheapened out on some features.
The auxiliary lighting option shown in the chart refers to interior foot well lights, a headlight buzzer and an engine compartment light. Both the buzzer and under hood light were missing on my car. I’m not sure what the story is- Either the factory screwed up, or the parts disappeared over time.
At this point I’ve fixed the headlight buzzer, and here’s a hot tip for anyone with an A, B or G-body GM – This is a “plug and play” modification. You can either comb the junkyards for the part, or pick one up on E-Bay. With the upgraded part in hand, pull out the seat belt buzzer and plug in your new part. Done.*

At a minimum, the sport mirror option added a joystick in the driver’s door panel to remotely adjust the driver’s outside mirror. The option may also replace the base chrome mirrors with aerodynamic sport mirrors but the available information is not clear on this point.
On a side note, the ’86 and ’87 El Camino use the same sport mirror housing as the Camaro and Corvette. As you’ll see in a later post, I took advantage of this fact to improve driver convenience.
The car came with a mid-level radio, which remained in place when I took possession. Delco actual builds a pretty decent radio, and I don’t like to chop up the factory wiring harness, so I planned to stick with this factory radio.
BUT, my buddy Paul had a top of the line cassette player unit out of a 1992 Bravada. As it was just “Sitting on the shelf,” I got it for nothing. A few illumination bulbs were burnt out, so I disassembled the unit and replaced the bulbs (kinda complicated- lotsa screws and one bulb required me to break out the soldering iron). Thanks to this gift, I now have a graphic equalizer and a working tape deck!
I mentioned the last two options in my initial posting. The first is comfortilt (tilt wheel), and while I could install this option, used GM steering columns aren’t cheap, so I much prefer having one on the car. The second option, a 22 gallon tank appears on my RPO Tag (build sheet), but I’ve yet to put more than 14 gallons in the tank.
I suspect the tank may have been replaced at some point, but I may be able to address this issue without buying a new tank- I’d like the extended range of the 22 gallon tank, but I’ll take this project on some time in the future.
Now that we know what came on the car, let’s talk about what I want on the car. I’ve identified these desires using yellow boxes in this chart. I’ve already added some, and plan to add all of them moving forward. A given upgrade may be straightforward and very inexpensive (such as my free tape deck), or it may require extensive time, effort, or money. I’ll explore those issues for each desired option in this section.
First up is electronic speed control. On most GM vehicles, adding this feature is quite simple, and that was true for my truck. I bought the needed parts in the junkyard, and installed the system over a long Saturday afternoon. I’ll cover this installation in a later post, along with some advice for people who would like to put this improvement on their own classics.
Next up is a limited slip axle, which I don’t really need here in SoCal. However, my long-term plan is to move back to Denver, Colorado, so it’s a desired feature. How to accomplish this? Drive it to a shop and write the guy a check. While I understand the process, I’ve never actually set up rear end gears, so best to treat this modification as vehicle maintenance and let a shop handle it.
I can handle an upgraded battery a similar way- When the current one fails, I’ll spec out the biggest one I can fit in the space provided.
The car does not have a center console with a floor gear selector, so I’ll have to fabricate the mounts to install one However, we’ll also have to pull out the bench seat and install buckets. Currently, the time line for this change out is “someday.”
Much like a better battery, everyone wants an upgraded cooling system. After my purchase, the original radiator did not keep up in mountain driving, so I replaced it with a heavy duty V-8 unit. At the same time, I replaced the fan on the water pump with a pair of electric fans, both for better cooling control, and for improved Air Conditioning performance during idle. Look for more details in a future posting.
I want the sport suspension, but the change out involves many parts. However, outside of a rear sway bar (which my car did not have), the project only requires upgrading existing parts. I’ll review this process when we take a look under the car.
As you saw when I reviewed the gauge package, the car came with a metal plate where the tach goes. I’ve modified a V-8 tach to work, and we’ll review that next week.
My truck did not come with bed tie downs, but I went to an aftermarket part to address this oversight. After installation, the “T” bars all rattled in their mounts, which I could hear in the cab. To fix it, I found some stick on rubber cushions at a hardware store which eliminated the annoyance.
Finally, the car needed intermittent windshield wipers. I spent quite a bit of time researching this option. You can install intermittent wipers on some Fords by simply swapping out a new wiper switch that has a control box built into the switch harness. Not so much for Chevys, so I’ll dive deeper into this modification in the future.
This final chart showing my overall plan with all desired options in green. Most of the blue boxes (options I don’t want) are appearance items, but there are two options I don’t intend on installing- Power Windows and Power Locks.
In both cases, I think the added convenience does not justify the added complexity, and both require me to cut or replace the inner door panels, an expensive prospect. For now, don’t expect any articles covering the installation of these features.
So that’s all. I hope you enjoyed this review of the El Kylemino’s features and some of the work I’ve completed to this point. Next week, we’ll take a closer look at that tach installation, along with repairs and changes I made in the gauge assembly while I had it torn apart.
I look forward to these future posts. It is interesting that the swap from bench to buckets/console is so difficult. I presume that you have never needed that middle for an emergency passenger?
And am I correct that the new electric fans eliminate the “ROAR” I hear from every 4.3 at low speed? Those things had the loudest fans.
“It is interesting that the swap from bench to buckets/console is so difficult.”
Not so much difficult as involved. At the factory, the additional seat tracks required four additional sheet metal pads. The pads are available in the aftermarket, but they need to be carefully positioned and then welded in place, so it requires some time and attention. In addition, junkyard G-body buckets and center consoles are now very scarce.
But it will happen in the future, perhaps with bucket seats out of a newer vehicle…
For some reason I’m totally geeking out over this. While I don’t really have any plans to own an ElCamino or related older GM vehicle this still somehow completely intrigues me and I look forward to seeing you tackle all these improvements.
Coming along nicely. All really cool but subtle and useful mods. And you are correct about how easy it is to add intermittent wipers on Fords; I did that very thing on my ’83 Ranger. Hardest part was reaching up under the dash to screw the control box in the factory location. You are also correct on the limited slip diff; except I wrote the check to Currie who built me a Ford 9 inch for said Ranger. (5.0L, 4wd longbed)
I remember collecting options off of junk yard cars to add to my ride. Gauge package WITH tach for my Chevette? Thank you very much. Added tilt wheel as well.
Maybe someone here know. What the heck happened to Comfortilt steering wheels/columns? (from Saginaw steering gear division:-) )
The newer GM cars with this silly friction lock set-up where the column pivots down near the floor – just doesn’t change the actual tilt of the steering wheel enough to provide me with a periodic change of position I like on long drives. There must be a reason GM got rid of it.
“There must be a reason GM got rid of it.”
It’s most likely airbag technology. It’s much harder to engineer a bag that works in all positions with large angle changes.
That. In the early days of airbags, getting them to work properly with ANY sort of tilt column was something of a challenge. (Recall that when Mustangs got a driver airbag, they lost the tilt option.)
I am sure it was the advent of airbags like Dave mentioned
But they were also troublesome. GM really did not know what locktite was as a lot of these tilt steering wheels tended to have screws that started to loosen up and that caused a lot of play in the steering wheel.
GM used 3 or 4 screws(I cannot remember) to attach the tilt part of the column to the lower part of the column. This allowed a good many adjustments to the wheel.
However when these screws unscrewed, you had a lot of play in it(you could grab the steering wheel when driving and move it up or down or it would sag downwards
To fix this, you had to dissemble the upper part of the column and remove a bunch of wires to get at those screws.
I did the repair on both my 85 and 87 Cutlass Supremes and my 1980 malibu
“But they were also troublesome. GM really did not know what locktite was as a lot of these tilt steering wheels tended to have screws that started to loosen up and that caused a lot of play in the steering wheel.”
Yes indeedy- Just made this fix last month, as the steering wheel suddenly gained a bunch of slop at the base of the tilt mechanism. We’ll walk through the process sometime soon.
I love these types of modifications. Upgrading to options that your car didn’t come with from the factory. I’ve done that a few times over, and I love reading up on how to do that. Looking forward to more of your tech stories.
Those factory tachs are hard to find, I don’t think I’ve ever seen one outside of a MCSS. I look forward to the articles to come!
I’m honestly shocked that GM still offered an AM only radio as recently as 1987. Did anyone actually order one, I wonder?
I added a set of power windows to my ’65 Chrysler. It wasn’t too difficult a project, but definitely time consuming. I can see that a mid size 2 door makes living with crank windows a lot easier than my full size convertible.
“I can see that a mid size 2 door makes living with crank windows a lot easier than my full size convertible.”
Exactly- I’m also 6’2″ with a long torso, so reaching the right side window crank is no issue at all.
I wanted an oil pressure gauge and ammeter gauge for my car, luckily the ,ocal vintage car club were having a clear out so they could move to new clubrooms so I scored a Singer gauge cluster for $5 and installed the gauges and they all work being a base model m,y car only had a temp gauge the others were extra cost options, I even fitted the correct heater in it another extra cost option the original buyer didnt bother with.
On my 1987 and 1985 Cutlass Supremes, I went out to a junk yard and got the fat rear sway bar and all mounting parts from a Monte Carlo SS. It was plug and play with the mounting holes already there.
As for the radio, I simply bought a Scosche wire adapter kit for an aftermarket radio. I wired the adapter wire harness to the aftermarket radio. Then I just plugged it into the factory radio harness and all was good to go. No cutting of the wire harness was needed. I used a scosche mounting kit so no cutting or drilling needed.
