So I bought an '89 for 600.
4.0 / 5 speed with Dana 35 (I think)
Mostly stock. The guy put a tree branch through the grill and replaced the radiator. But not the AC rad or the 2nd'ary fan.
The 'part time' light is perm on / so I think he didn't fix the vacuum line. It idles a little rough and tested rich on emissions.
I did the standard oil/plugs/wires/fluids...
There were 3 brands of plugs with 2 different gaps that I pulled out. The rotor looked like one of those magnetic hair toys when I was a kid. But black!
Also did the rear diff oil as there was 1 - 3 clanks in 1st depending on how much gas I gave it.
New synthetic w/ no slip add ~ and the clank is gone.

I ordered a set of reverb EV6 fuel injectors (4 hole) on eBay for 60. I'm also going to swap out the mechanical fan for an electric.
Then, down the road, I want to swap the throttle bod for an early 90's and do some exhaust upgrades.

Gonna pull the carpet and bed line the inside...
...as well as the outside.
But again - that's down the road. For now, just gotta get to legal.
