Had to do the same thing with my 07 Avalanche. Ended up costing 6 grand, but the guy had to basically rebuild all the seats. Foam was toast all the way through. If yours aren't in the horrible shape mine were in, the upholstery shop should have an easier time replicating yours. I was the last job this guy was doing before retiring and moving - talk about a going away gift.

Tex - had to do the same thing for all three compartments and the missing bow rider insert on my 07 Avalanche C4. Ended up using 3/4" HDPE. It was expensive, but I know it's not going anywhere and you can work it like wood. I used a jigsaw, router, and orbital sander to make mine. If yours have deteriorated to where you can't trace them, I would suggest using cardboard to make a template. Don't forget to allow space around the edges for the upholstery to wrap around. Also, there is about an 1/8" "notch" along the piano hinge. I can try to dig up some pictures of mine if that will help.
