I have a 74 Comet gt, it was fairly rust from the start and the rear frame rails were complete gone. I built new rail and have them moved in 5 1/2 inches on each side for tire clearance, does anyone have the underbody frame measurements? I can adjust the measurements for what I need. It would be very helpfull to be sure everything is in place before I finish welding.
I have the frame charts. PM me an address and I will try to mail you a copy. Or email, if I can scan them that well.
