My door panels are shot and I want to change them. The problem is the junk yards are pretty much picked thruogh. So my question is what kind of board is on the back of the panel? and where do I get it? I'm going to just use tan replacement carpet on it? Any ideas?

OK I found some 1/8 2x4 mdf panel that's almost the same same as the the pressed catboats. And it trims easy with a razor. And today I will get my tan replacement carpet.
