Re: Replacing 1969 trunk pan
I'm going to give you my honest opinion having been involved with a trunk pan replacement in multiple pieces and one-piece replacement: the final product is VASTLY better as a one-piece replacement. It may look like more work up front, but it's really not in the end. It requires patience and the realization that it's not a weekend project for a first-timer.
Getting the seven-piece replacement all lined up and then looking remotely decent in the end is extremely frustrating, and the end result looks noticeably inferior to the one-piece if you don't' do this stuff for a living - and I don't! The one-piece has all the braces pre-assembled and obviously you don't' have weld seems running everywhere that often require enormous effort and patience to get looking half invisible.
The full truth of it is, you'll likely realize once you get the trunk cut out, the surrounding metal may very well need replacement also. Whatever you decide, when it comes to floor and trunk pans, bracing is very important. Here's a picture of my 71, which ended up going from " we can get away with patch panels" to "new floor pan, trunk pan, trunk extensions, all inner & outer wheel wells, seat divider, package tray, and one quarter panel".
Don't want to rain on your hopes, but I wanted to give you an honest opinion before you embark on the journey. Certainly, you can just do the trunk now and the other stuff later. Obviously it's more total work that way, but that may be what one's finances dictate.
Whatever you do, hit up Youtube and all the old posts here. There's a wealth of information. The seven-piece kit is doable, but looking back I'll never go that route again after doing a one-piece. I would definitely research long and hard at both the seven-piece installation and the full trunk installation before committing one way or the other. You may find it's worth the expense of not using the seven-piece and paying for a one-piece.
