I have a 57 Tbird, and the passenger door doesn't fit properly. The front edge rear top fit flush but the bottom rear flares out 1\8 inch from the door handle down. There appears to not have had any body work in this area. Also I have to replace the glass for a second time as the inner laminate has spontaneously cracked and has sevreral cracks but the outer layer is unbroken. Any clues as to what's going on?
