Welcome to the forums Joseph!
TBH. I don't know what hope there is for you knowing you used a Pentax lens on a Nikon body for years. I mean sure... people have done this in the past, but in most cases we were looking at accidental mounting, or sheer ignorance. But in your case.. were talking years of deliberate sinning against the Pentax label, and so honestly, I don't know where you stand with that.
PS. We are not a cult! Just take a picture of you burning your Nikon body(in your backyard) while holding your hands toward the heavens and post it here for all to see.
PS2. Welcome once again to the forums though. No really... were happy to have you. Don't forget to share some pics. And don't forget to look-up the market place. It is a literal treasure-trove of M42 lenses. You'll love it I'm sure.
Sincerely,
JohnB
