Sorry, I don't have access to the RV at the moment, so I can't show the part separate from the door. I've attached photo of a plastic piece with screw in center. This was mounted in a slot in the wood door at the back, bottom of the door. It appears that the plastic piece needs to move up and down slightly and according to Jayco Forum, but I have no idea. This looks a lot like your 23-215 or 23-026 except mine doesn't have the metal framework, just a wooden slot in the door. Will either of your noted parts work and if so, how are they installed? Also, if you have exact match to photo kindly advise. Thank you for your time.
