I'm dismayed to hear about your issues with Classic Parts. Awhile back I ordered their cab rubber kit (window gaskets, etc.) and have it on the shelf waiting for the day I get my cab to that point. I was just thinking of ordering their door kits. After reading about your experience, I'm not sure I will, and am now concerned about the fit of some of the items in the cab kit. And by the time I can actually try to install them, it will be too late to do a return. I think I will instead purchase the items I need individually so that I can deal with the problem ones as they arise. As an aside, I've already used a lot of their items when I rehabbed my chassis, and did not have any issues with anything at that time.
