No its not the original rearend i dont think. 2 pos back put in this 10 bolt, so i had the wheels made with 5 1/2 "" back space, wich is what you see. There is still a few inches of clearence. Id like to bring the wheels in a littel more, maybe bigger wheels, maybe just less backspace, maybe shorter houseing with tubs, I dont know. I guess the first step will be to to inspect the rearend and see what it is, and what shape its in.
