I bought 95 orvis 5.2 . It has full 5.5" rusty's w adj track bars. I drove it home and parked it. Then it snowed like a bastard for 2 months and I can't even get started it's too ****in cold. So I got wires on top of the motor that don't go to anything and I'm missing an AC compressor and it was hacked out with a machete. Got a o2 sensor code and it runs rough but it is not knocking or ticking at all. I got a full time 4 model so when I put it in 4 low it don't go anywhere and front shaft is stock but not in. How long does it have to be what do I measure where to where??
