I would have to travel at least 150 miles to find a frame shop. ...going to crow all over the undercarriage and try to make a decision..................
Do you have the Factory Body Service Manual? If not you need to get a copy for your year and make/model. In the back of the Body Manual there are body and frame alignment dimensions. You can use these to determine if you're frame/body is out of spec. Park your car on a flat level surface (your garage), use the reference points in the manual, use a plumb bob and mark points on tape stuck to your garage floor.
