67 barracuda notchback restoration

I just jacked up the *** end. Talk about a flexible flyer. I got 1/4" door gap in the back at the top and bottom. I had no idea it would move that much. Still doesnt explain why i had to slot the crap out of the hinge holes in the hinges and the body and move it waaay back. The slotted holes should have had enough adjustment. I really dont want to push the door back any further because of the weatherstrip maybe not sealing good at the front if i do that.
