Well, I was gettin in to the nitty gritty of things today and ran into a problem.
I removed the bed and about 6 inches back from the cab, the frame has been cut and re-welded in what looks like a hack job of a shortened frame attempt. It looks like this frame was a long wheel base and someone decided to go short. Along with the crappy c-notch for the flipped axle, I'm not to comfortable putting over 500hp to the rear wheels of this frame.
The build is gonna have to wait until I find another suitable chassis.
Anyone know if an 81 will fit on an 88 frame? My buddy has one that he'll give me.
