Body mounts/bushings, sagging ??

[JWMcCrary]

My Bronco has a little sag at the body mounts where the fenders and doors meet. I gave a little look at this before buying and thought all it needed was new bushings. After investigating further there are cracks in the body around the mounts and it seems it has been bent some. There doesn't appear to be any rust. Has anyone done this type of repair to theirs? Would straightening it out and welding it be good enough?
