Does anyone know where I could find door panels? I tried Cal Pontiac Restoration, but no door panels. I would like to get new/replacement panels as opposed to used. Does anyone know a source of good interior parts before I go to an upholsterer? It's a 1956 Pontiac Chieftain Catalina, 2DR HT.

I'm also looking for an original radio/speaker and a set of plastic knobs for the dash. Any help would be awesome. Thanks!
