I have a '73 challenger. It has the horrible 70's sun roof cut into it. They missed the support. Can this be welded up? I'm a pretty good welder and have all the tools I need. Now I know I'll get a"just put a skin on it!" But that is over 600.00, so if it is possible to weld it that would be worth a shot. Has anyone actually welded one and had it come out ok. Thank you!
