At this point, the trunks are pretty much the same....2 piece units that require a lot of fitting. Goodmark is rumored to be coming out with a one piece pan in the new year, but don't hold your breath.
There are really no good mopar-specific restoration resources, except for some internet sites. Books on the e-bodies are thin and not really complete. There are various books and resources on restoratios in general. I ordered "The Collector Car Restoration Home Video Libary". It's alright...I picked up some good tips. Try
www.carestoration.com.
There are multiple bodywork videos out there. Kevin Tetz offers the Paintucation series and it's definately worth picking up. Also make sure to hit
www.metalshapers.org and
www.autobody101.com.
Just about everything you are going to do to your car has been done and documented in great detail on this site. I know I posted my trunk pan replacement saga. Some of the older posts will be missing pics, but if you have a specific question, you can always email the original thread poster for the original pics.
