Thought I would update this.
Turns out cj5 is more of a mutt than i thought; 81 body on a 78 frame. Engine is an AMC 360 but out of something older than 82. I assumed previous owner had a title but we just did a bill of sale, good enough to get my stuff. After I told him I couldn't read VIN on firewall he sent me the old titles. Yes, plural. He never titled it since it was a toy so I have 2 crusty titles but only need the VIN for body, so cool I'm cool.
I followed a classic car start up guide and used marvel mystery oil in cylinders for few times before starting. Oil change, new plugs and coolant and first nice Sunday few weeks ago I rolled it out. It didn't run except for starter fluid I poured in it. Huh. I didn't realize fuel pump had a diaphragm in it, I assumed it was a valve thingies so first time I tried to start it, it pulled no fuel from can I had set up. I got a pump week or two later and now it's on. I also found 2 fuel lines along frame rails with only one being used. Pulled them out (going with rubber all the way to tank), also pulled "roll over check valve" and charcoal canister that were bypassed but still bolted up inside fender. Originally planed to clean and re-use tank but after I pulled it and found rust spores and peeling liner I decided not to. Found a tank assembly and skid on ksl and bolted it up.
I sold off the crazy wide rims since I didn't want run a 14" or wider tire. Grabbed some 15x8 from someone who was moving and selling for cheap. Going tomorrow to get some 33" MT and toss them on.
once that's done, I plan to roll out of garage and fire it up, again.
