1989 GMC Sierra SportSide
Sierra isn't a show truck but she does show off my mod skills.
![]() A few pics of how she looked when she hit the road. ![]() ![]() ![]() How she sits today, not much different except a set of 15x8 squarebody rallies. ![]() How she will look one day only in the original Brandywine/Garnet Red colour. I was looking for a 1988 GMC but I couldn't pass up the truck though it's one year newer and only diehards would notice the differences. (radio and HVAC colours). There were a few Brandywine/Garnet Red replicas made. ![]() I only paid $800. Needing an engine rebuild. For $300, I bought a good running 350 TBI and switched them out. Has never left Texas ever. Two previous owners, both older folks. No rust what so ever except a tiny bit of surface rust here and there from the peeling paint.

Re: 1989 GMC Sierra SportSide
Future mods include a 1992-94 Bonneville bench seat, later heated mirrors, who knows what else. I have been contemplating integrating a 2002 Trans Am Body Control Module.

Re: 1989 GMC Sierra SportSide
New pics. Certainly not the prettiest girl at the ball, but she's curvy enough to make heads turn.

Re: 1989 GMC Sierra SportSide
Thanks!
I must be doing something right, I've had no less than 5 offers to buy her just this week. ![]() Got her a new seat last week for $20. Except for a major cleaning, new speakers and I'd like to find a set of 1992-94 Blazer/Yukon/Suburban door panels, the interior is about finished.

Re: 1989 GMC Sierra SportSide
Great build, I've always liked integrating parts from other vehicles(especially different makes and/or models), and I have a couple questions: How much room does the tilt/tele column mod take? Is the steering wheel closer to you now? Did the Vette wheel compensate any?
Is the auto down window mod in the switch, or is it a module that could be obtained from other cars that have it, and use the original(truck) switch? Remote keyless entry: Is that a module too, hopefully? Do you have to find one with the key and doorlocks to match? I own 3 of these vehicles and change parts around frequently, altho most of mine are simple upgrades from newer models of the same platform. I have done the rearview mirror, Hi-4 headlights, sunvisors (Chevy Astro IIRC), cupholder, Jeep lower column, Escalade wheels, some others on my DD Yukon, but you have taken it to a new level. Love the OEM low buck approach! Planning on the hydroboost and brake upgrade soon also. What about the stereo amp? Is that the whole unit that fits in the original dash opening without modification, or a separate unit that could be hidden anywhere? Thanks for the info in your thread and keep us posted as you find more great mods!

The Vette wheel is about 1/4" closer when it's fully retracted. The wheel is slightly smaller than the original wheel but much thicker (which makes it a lot more pleasurable to drive, IMO.) Quote:

The amp is also the exact same as the amp it would be replacing that's under the dash. I like the Buick amp because it has a MUCH cleaner sound than the original. I just grabbed one from a 1991-93 Park Avenue/LeSabre with an EQ cassette player - Olds 88 and 98 would work as well as would one from a CD player but those are hard to find and when you do, you can sell it for big bucks as it's the exact same as the Typhoon CD player - I bought the whole radio for $8 and only used the amp which is detachable and then modded it for the AUX input (which was NOT easy!) and I ran the cable for that out the ashtray.

Re: 1989 GMC Sierra SportSide
Nice. Somewhere I have a pic of my truck parked under that sign from '98. That was before my digital days.

Re: 1989 GMC Sierra SportSide
I can't wait to get these installed.
![]() Next week though, new hinge pins and bushings as well as door strikers as mine are getting badly worn and rattling. Only rattle in the truck. My friend who has a brand new Dodge Ram was very impressed with how quiet it is for a 25 year old truck even compared to his new one.

Re: 1989 GMC Sierra SportSide
I would be interested in how hard the mirror setup was to install, I have a 98 and I am not an electrical genius. I assume the wires run under the headliner? Does the factory computer have all the connections or are there splices to build?
Thanks. |

Re: 1989 GMC Sierra SportSide
Jay, I got the relays for the windows a couple months ago, finally got around to the install today. Your writeup was invaluable, as I had no idea what to do just from looking at the relays. I put 2 on the D/S door, so I have auto down on both windows from the driver's seat, gonna get another and install it on the P/S door. I sure wish there was a how to for the amp and RKE upgrades also, an "electronically challenged" guy like me needs it

I have put some write-ups on the 454SS/NATC board as well. I keep working on them. I will have the RKE write-up done soon. TO install it, you will need a power lock relay, as trucks without RKE didn't get them but SUVs did. I'd do a write-up on the amp but my schematics were destroyed by water and I need to get another set. This is the type of stereo I got the amp from: The amp just unbolts from the top of the unit and I have yet to come across a bad one from one of these.

Here's the latest pic. Showing off the tilt/tele wheel, mirror, gauges, cupholders, RKE, the AUX input. It's amazing that I've been able to find nice interior pieces so far and that my dash doesn't have a single crack in it even after baking in the Texas sun for a year. The carpet is really nice too. I will end up putting in 1992-94 Suburban/Blazer door panels when I find some decent ones so I can add power mirrors.

Re: 1989 GMC Sierra SportSide
Replaced the o-ring in the back of my 700r4, usually when I parked her in the driveway she would leak a quart in minutes, not anymore.

Yeah the brake fade is really something I should have addressed well before now. I personally don't plan to do the rear discs, seems like too much $ at this time. Some are working on adapting available parts (mounts) instead of custom fabbing them, which, if accomplished, will get the cost down and I might do it then if the cost/work/benefit factors are favorable. The front brakes do like 80-85% of the braking anyhow, so that's the place to concentrate first, to me. Have you considered the Hi-4 headlites yet? A cheap and simple upgrade that should be right up your alley considering your electrical skills, and yeilds outstanding benefits for the work. I personally took it to another level by wiring in a toggle switch (mounted at the bottom of the dash near the parking brake release), so I can have either just the low beams, just the hi beams, or both. Has worked out well so far and is one of my favorite mods. Now maybe some auto-dimming headlights adapted from a Caddy or something? ![]()

Re: 1989 GMC Sierra SportSide
Well. I said I wasn't doing any mods for awhile but I was wrong. A set of Escalade mirrors fell in to my hands for cheap so now she will be getting power heated and auto-dimming side mirrors.
