Welcome from the Pacific NW. You have a nice looking Jimmy. Post some more photos when you get a chance.
I have seen "custom" rear interior panels in the pickupsnw catalog. They don't list them on the web site though. I think they were around $400. There is a tread on making your own door panels right now. I'm sure that the same would apply to rear panels and maybe the dashpad. I plan on using a Tuffy consoles so my stereo is secure(
