Default 71 77 frame differences ?

I have a 71 body and can get a pretty complete 77 frame (most of a rolling chassis including suspension, rear axle, brakes).
I know the frames are different, does anyone know what modifications are needed & what parts are usuable?

77 has the rear crossmember designed for rear bumper impact shock absorbers.

You have to replace the rear section of the frame from roughly the center of the rear hub line vertically. You will also need to switch to rubber or urethane body mounts because the mounts are located differntly for solid mounts.

Here is a 78 chassis I used for my 73. I used a section of the rails and rear crossmember from the 73. I staggerd the cuts between top half and lower half of the rails.
