need some body work help from the metal guys....

[Taylor]

on my '67 beater both doors were sprung at one point or another and I need to fix the quarter panles now.  My question is on the front quarter panles right in front of the rain lip there are dents from the doors opening to far so before I get in there and beat them back out, how do I make sure that the metal will go back under the lip fold.  If you know what I mean.    Or in  other words the doors opened to far and pushed the metal out from under the lip
