1001 produced = very hard to find parts for.
GMC = strange non, truck parts that are hard to find. (Had a New Look Fishbowl I know how hard suspension and steering parts are).
This one is rough and I bet it needs a small universe of things done to it.
On the bright side, there isn't anything to rip out.
No engine picture.... could be really frightening. Mine dribbled oil everywhere it went. On the bright side, I had a 6v71 V-drive 4 speed. It was thrifty with fuel. 10 MPG from NC to TX daring to do 65 mph. Mine had a wierd wet clutch system and a 90 degree transmission. I've never seen anything like it. It was impossible to access and the whole time I owned it I prayed nothing bad would happen to the drive train.
