I am a newbe here so bear with me. Does anyone know where I can get aftermarket rear cargo parts for my 08 LS Panel ex parts chaser I recently purchased. It is a great vehicle and really like it but the cargo area is in bad/cracked /broken. I want to replace the front portion for sure, Thanks to all of you for your help

 

Check local scrap yards. That would be my first thing to do. They may have one may not but it's worth a call!

 

The REAR interior parts except the rear doors are the Same interior parts as in the Panel.

Exception is GM placed a color matched plastic Cover for were the rear quarter glass would have been.

If your quarter glass Inserts (covers) are still OK, you can just Reuse them.
And if not, it's EASY to make a pair out of abs black plastic sheets sold at Menards near the Window Dept. One side Smooth and one side is Grained like our interiors are.

The Insert comes out With the upper rear quarter interior piece, once out you can remove it and use it with your new/used interior pieces.

Several of us Panel owners have even Added a Rear Seat from a Windowed HHR WITH the Seat Belts. It's a straight up bolt in Swap.

 

Which parts are you looking for exactly? I have the storage box that I took out of my panel to install the seat if that will help. It has all of the black plastic trim that goes with it as well.
