So the frame rail is actually attached to the body, unlike a GTO in which it is actually a separate part.
It sounds like if you have a bad frame rail its is a pretty big job to fix. I will need to make sure I check any potential cars for a solid rail.
Thanks for all the replys, it was really helpful.
PS. I assume FRITO is not asking real questions because NOBODY seriously has that bad of grammer, puntuation and spelling.
