Charles, Do you mean the backing board the upholstery attaches to? If so, you can use plastic board stock. I read about it in a street rod magazine. I can't remember if it's styrene, ABS, or urethane. I think they use ABS. I haven't done it yet, but I want it give it a try on one of my other projects. I have a pair of door panels that the skins are good, but the board is falling apart.

Or if I cant find that where to get the org material?
