Simple way to replace inner wheel well lip and Quarter panel install tips!

I have a 65 Dart GT with some serious rust issues in the quarter panels and floor pans. The trunk and rear pan areas are in the same shape, and a previous poor repair didn't help. I have a two-post donor car that is good all the way back. I'm considering doing a rear clip from the back edge of the door opening all the way back, but leaving the rocker panels intact on the original car. Do you (or anyone) know of anyone who has done a rear clip on one of these cars, and how they did it?
