I ordered a door skin for my Cuda' from Classic Industries (talked to the guy over the phone) and asked if it was an AMD part and he said it was a Classic Industries panel and did not know who made it. A week later the door skin shows up in a Classic Industries box. I pulled it out of the box and the skin had the standard AMD label on it, so it turned out to be an AMD panel. I'm not sure this is always the case with sheet metal from them but it was for the part I ordered.

It can't hurt to call and ask, you might get a sales person who knows more then the guy I talked too.
