There is no price list for this stuff. Gotta just find doors near enough to avoid shipping. Start watching Ebay and craigslist in surrounding towns. Put a wanted in Stovebolt. You already know they are not plentiful. You need to know what years will fit, 41-47.1 ???
BTW: Do you know that truck cab doors are not the same as Panel/Suburban doors?
