The 2nd pic with red door is indeed a 514 red primary color truck - my all time favorite swb big block bucket am/fm Super on the planet, sameyrasmea's...

I've been trying to figure out this oddity for a while. I've asked friends of mine that are into these trucks as parts collectors/sellers, and restoration shops. One of them has never seen any of these. The other says he believes GM had a surplus of black cheyenne super glove box doors painted black and they just sent them to various plants to use them up. Personally I don't think that is the reason. I don't have a good answer as to why these are this way though. I used to think it was plant specific too. Everything pointed to Flint and Janesville plants sending these out. Here's a St.Louis one, my GMC is a Flint, and I have a Janesville one that is on a medium red truck.

Here are a couple examples of black cheyenne super doors on non orange and red trucks. First is a grape whine/yellow and white K20 I've been trying to buy for years. The guy just wants too much for it. The 2nd is my 72 GMC in medium olive.
