    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    Here's the adapter fitting for the brakes when eliminating the RWAL. And I also went and pulled this greasy lump out of my old Camaro. It's been in unsecured storage for about 5 years (an old 16x16 vinyl military tent on my parents' property), and sometime during that time someone went in...

    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    Just a few little jobs done today. Got all the cotter pins in the spindles and balljoints. Removed the rear antilock brake module. Just waiting on a adapter fitting to get it buttoned up. Started putting the interior back together. Finished de-gunkify-ing the trans and got a couple of...

    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    I don't have my shop built yet, so no wiring in place for a welder. It was easier just to slap down $7 at the parts yard for another caliper, but someday I'll get a place to really work on stuff. The goal of the build has changed somewhat in the past two years. Since I have a pretty successful...

    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    Got it pretty clean with more brake cleaner, then dropped in the o ring seal. I lubed up the piston and put the dust boot on it first, then pushed it slowly but firmly into the bore. I then took a screwdriver and seated the dust cover into its machined bore. Then I pushed it back and...

    You'll have a nasty mess because brake fluid absorbs water and nobody changes it like they should. So I cleaned up the piston with a little brake parts cleaner. And then pulled out the dust boot. It can be a little tricky; you have to drive a screwdriver in the edge of the seal and pry it...

    So I didn't take a bunch of pictures of the suspension reassembly, but it's pretty much just the reverse of disassembly. I greased up the polyurethane bushings and jammed them into the old bushing shells, then reinstalled the upper and lower arms. The springs and spindles went in next (4"...

    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    The lower control arm bushings ended up being a big ole PITA. I ended up using a hole saw to cut most of the bushings out, then using my shop press to punch out the center metal sleeve. I was then able to collapse the remaining rubber on itself and push it out. The results were pretty good...

    So I yanked the motor and trans. Went to the u-pull-it yard and got a clutch pedal and bracket, then got them installed: Installed a new clutch master and hydraulic hose: Then I blew apart the front suspension: And started to burn out the old suspension bushings in preparation for...

    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    Holy back-from-the-dead thread, there, Batman! No I didn't die or get rid if the truck or anything; just got distracted by life and stuff. The truck build was going to take forever and I really wanted to go autocross racing, so I bought a car off copart and fixed it enough. I've spent the last...

    Tbi to Carburetor

    I like the simplicity of a carburetor, and the more authentic driving experience. I like pulling on the choke, cranking the engine, then warming it up. On a secondary vehicle. On my primary I want to jump in and go and let the computer do the work. All that being said, I like the Edelbrock...

    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    Had a couple of hours today to work on the truck. Finished gutting the interior. I will probably pull out that firewall insulation. I just got a copy of the newest version of the SCCA CAM-T rules and it did mention having a stock appearing interior, so I'll have to put most of the dash shell...

    Won't start and only 1 click at the starter ?

    Steering problems. Can't figure it out.

    My guess is alignment or tires. I worked in a tire shop when I was younger and we had a guy bring in a F250 with a similar problem. We noticed a little wear on some of the suspension components and ended up doing over $2000 worth of work rebuilding the whole front suspension. Still had the same...

    I wish you were closer. I haven't been having any luck finding a heat only box. It gets so hot down here that AC came virtually standard on every vehicle after 1980. I've actually never seen a GMT400 heat-only truck. I may have to do one of those campy little cigarette lighter defrosters and...

    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    Didn't get a chance to do a whole lot to the truck this weekend, but I did manage to start cleaning out the interior. There was some interesting stuff in there, like a couple of big rolls of 55 gallon trash bags. There was also a very nasty looking butcher knife, a golf 9 iron, and several...

    Transmission Fluid Dripping From Front U-Joint

    If the new rear seal doesn't fix the problem, it's worn splines on the driveshaft yoke letting fluid past them back to the weep hole in the rear center of the yoke. Quick and dirty repair is to squirt some RTV or "right stuff" into the weep hole to seal it up. Correct way is to replace the yoke.

    Tire Size ?

    That's a pretty skinny tire for a 8" wheel. That tire is probably best suited for a 6" wheel. 7 is probably the max for that tire. The 215 could probably be mounted on the 8" wheel but it will look a little odd.

    "Lt. Dan" - 1989 C1500 Regular Cab SWB NASCAR tribute and Autocross Build

    Scored a pair of seats today for the truck. They are some kind of military vehicle seats (We have a military depot nearby that rebuilds all kinds of APCs, tanks, and humvees, so this kind of stuff is pretty common around here). The cool thing is that they have integrated 5 point harnesses with...
