    Default Newest pile - 1989 GMC Sierra SLE SportSide

    Couldn't pass it up for $800. Factory 350, auto, pretty much all the options and most of them still work, 3.08 axle (that's gotta go). 2 owner truck (old lady and her brother), has never left Texas and has ZERO rust on the body. Frame has a lot of surface rust from sitting for the past 8 months. Amazingly the dash isn't cracked and the interior - except for the seat and headliner - is really nice. Too bad I hate red.

    Of course it will get my own brand of mods.





    I want one of these now...



    What it will eventually look like...

    That's a nice truck, I wonder why they sold it for $800? I'm guessing it's a combo of the age, paint condition, etc. How many miles on it?

    My first new vehicle was an 89 GMC Sierra ST. 350/5-spd, 3.42 rear. Same color as that with silver lower and SIERRA ST on the lower doors. Mine was a fleetside.

    Just had gotten new 15x8 wheels, still had the nasty old tires. Still have the original wheels like yours, mint. The new tires ended up being 275/60/15, same as the 454SS. The pic is from 1991 at Nellis AFB, NV.

    Its exactly what I have, except mine is a longbed... its sucha shame that these run so well that they start to become worthless because there are so many out there. I also picked mine up for 800, with 4 brand new tires, but mine is a work truck witha 305 and it shows. However the stepsides are worth something, my dad picked up a low mileage one a few years ago identical to yours that was near perfect and sold it for $3500. I've got a feeling you got a deal because the woman knew you would take care of it and she needed it gone. I got a deal on mine for th at reason, but not as nice as you just got!

    Mine has 275/60/15s now. I LOVE the STs and GTs. There's an ST SportSide that hasn't moved in 20 years not far from me.

    Got the A/C working today (must have down here) and scraped off all the old window tint in hopes to get them retinted in a few weeks.

    That thing is begging for an LM7. I'm sure someone on the internet has done it and has done a write-up.

    LM7 is the 5.3L V8 from the 2000+ trucks. More power and torque than that TBI 350, and better fuel economy. It's also part of the LS engine family, so you can do silly things like bolt on heads and intake from the LS1/2. Well worth it.

    Nah, I'm going to keep it old school with an L98 (350 TPI).

    Here's what it looks like underneath. Still has the tags on the springs. Sorry for the big pics.

    I would've dearly loved to do a TPI mod on mine back in the day. I remember Arizona Speed and Marine was the he-bull of those swaps back in the 90's. Don't even know if they are still in business.

    Just checked, they are.

    That's probably why you got it cheap. Not that it doesn't still have a lot of life left (plus they're easy to work on should you have to), but most people lack the mechanical know-how and all they see is a stack of miles. That is amazingly clean too.

    200k is nothing on one of these provided the body is rust free. That is a damn nice truck!

    I wish I could have that 3.08 rear in my Suburban to see if it can crack 20mpg highway. But I can't give up the 3.73 posi in there now and I proved on the trip up here to Ohio that it can get 18.4 or something like that if I don't ever exceed 62mph and run the AC part time, even through OK-MO-IL hills.

    First actual mod.



    Jeep XJ steering shaft. 1/1000th the price of a Borgeson shaft and works the same.

    Really tightens up the steering as it eliminates the rag joint which is just a piece of thick fabric that is supposed to stop road vibrations from telegraphing up to the steering wheel. Also gives a better on-road feel.

    My column is surprisingly tight, I will be taking it apart in the future though and putting loc-tite on those bolts since I will have it apart to add the telescopic like I had done to my S10 Blazer.
