I am having the hardest time finding a catalog or any source for these plastic trim panels that sit between the doors in the sedan. I want some for my '75 Deville.

Any ideas??

B-Pillar? ou mean the B-pillar between the door jam that has the carpet on it right? My Electra has that, but if you are talking about a coupe DeVille I have no idea. The hardtop bodystyle eliminates the B-pillar in the C-Body cars. Your best bet is on eBay.
