Well, I was able to get that door from a shop in Hamburg - the only one selling Pentax spare parts here in Germany. But if you're based in the US, you might find it easier to find a shop over there. However, I never really fixed the issue and the spare-door is still unused. I was not able to figure out how to replace the door without fully de-mounting the whole camera body - which is something I would rather leave to experts than do it myself.
