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

Does your frame / body guy realize that an A body Chrysler product is a unibody? That frame rail is welded in to the floor, inner fender, rad support etc. It is a large undertaking to replace it, and it should probably go onto a frame straightener after changing the rail to check it out dimensionally.

Just wondering, perhaps is is thinking it is a bolt in stub frame like a Nova?

If the damage is only forward of the lower control arm mounts I don't see why you couldn't section in a new piece.

What body panels are you having difficulty aligning?
