Made it out to the farm this weekend and spent a little time with Paul. Found out that it came with 4.10 gears and a locking rear differential. Also found the adjustable rear brake bias with the squat arm thingy attached to the rear axle. Pretty sweet stuff.
Paint isn't as bad as I thought, I just hosed it off and it looks 20 times better.
Looks like he put the seats down in 1987 and then put the plywood and carpet over the cargo area and never moved it. Seats are mint and rear carpet is pretty damn good looking!
Unfortunately due to a leaking hydroboost the front carpet is done.
I ordered a bunch of parts for it yesterday: belts, air filter, oil filter, fuel tank straps, tank sending unit lock ring and seal, u-joints and steering damper. Picked up two new 78 series batteries from Costco, funny the tire guy there said, "Diesel Chevy?"! Haha!
We'll see if I can get out there again next weekend and get the new parts on and have it running when Uncle Paul comes up for the 4th! Would be great to have him see it running.
