Hi Ron, I think a thin pillar coupe and a 2 door post are the same body style, just that thin pillar coupe sounds fancier than apost car. It is a Buick afterall, can't be a plain post sedan or anything like that. Is there anyway you can post a pic? Both of the cars I am working on have the frame on the door with bright work trim for the glass to set in as opposed to a true hard top. If your doors are what I need I'm interested in them as I need a passenger door badly and wouldn't mind a spare driver door as well. Thanks, Doug
