I am in the process of replacing the rear frame member, right behind the rear bumper. Can some one tell me the correct inside to inside frame measurement. The old member was used to pull the car( before me) and was bent way out. Also, has any one had to replace a broken body mount nut cage. If so please give me some advice. I had to drill a hole to access the rusted one and discovered that the cage was broke. Please help
thanks

if you search hear somewhere i hav posted the frame measurements. but i forgot what they are now. what you should be boing by is the center of the body bushing holes dimensions. that is what is important. also i have had this problem before and if it is at all possable to just bend it back you might be better off then welding in a new piece. i was able to bend mine back in place.
