I just did mine in my 69 Z. Man, that had to have been the hardest thing that I have ever done on a car! I didn't want to take a quarter off and go from the side, so I decided to go from the back (remove rear panel). It "appeared" as if it would slide in with minimal effort. Yeah right. I had to slice the right wheel well as the trunk pan itself is about 3/4 of an inch wider at the front. Oh, and had to remove the trunk hinges along with their brackets. Then came the "massaging" (beating) it down into place. Once it was all said and done and welded into place, I found that my AMD trunk pan was 3/4 of an inch too "short" at the tail panel. Had to slice the rear lip of the trunk pan and butt weld a 3/4 inch 18 ga piece of metal in to lengthen the trunk pan. Upon reasearching it appears that this is a common problem. Just something to note. If I were to do it all over again, I would chose the bottom up route (remove the frame rails). I think that this would be the easiest solution. I shied away from it initially because I was concerned about losing the factory weld appearance underneath the car. By going through the rear tail panel, a lot of the welding locations can simply be ground smooth and hidden under spatter paint. A complete trunk pan would never fit through the trunk lid opening, period. This project is not for the inexperienced.
