Hey All i'm working on an 88 Jimmy. I found this truck with all new floors alrady installed and most of the mechanical work done. I'm in need of some advice with the interior work. There are a few missing pannels and such. I am most concerned about the back of the truck. I'm not really sure what the interior is suppose to look like and how to finish it. Not to easy to find parts here in this neck of the woods. Any suggestions??
