I have a 71 GMC, it lays rockers, what I did is notched the crossmember 3 1/2 inchs and then I took some new rubber body mounts and cut them in half, lays rocker pretty hard, everyone said that I would have to raise my tranny tunnel, but all I did was notched the center of the front X-member for room for the oil pan, made new motor mounts, now the motor sits in the same place it did before I ripped it out, and the body lays, I found it pretty easy to do.
