Back half Dart

I was just wondering if anyone has done a back half to their A-body. If there were any major problems you ran into in the process please share.

I'm going to cut from the hack job sub frame connectors back to the bumper and hopefully keep the stock floor panels. My teacher did it to his Dart and he runs in the high 8's. But he back halfed it a lot different than I'm planning.

I've been back half-ing a 54' Vette at work and I am hooked. I know I'm more than capable. I was just wondering if anyone had any advice, and if you got any pictures that would be awsome. Thanks a lot. -Derek
