71 Twister with 340 4-spd, Bent front frame rails

From the doors back, everything lines up. However, the entire front end can't be lined up. Fenders, aprons, hood, grille, etc.
My body guy has a frame machine and does a lot of this type of work. He is going to disassemble the front end, cut out the bent sections of the frame rails (from the very front, to after the shock mounts.

If it's the entire front end, I would remove the whole front clip. You can't depend on any of those structures to be straight. Your best bet might be to find a complete donor car and just remove the front clip as a whole from the shell. That way the whole structure remains intact, and you just have to locate the new clip on your current shell. Otherwise, I would start from the frame rails and work up. Everything will have to be laid out and located. If your body guy has a frame machine, he has the tools to take care of it.
