GrouchyOldMan,
Thank you for that link. I just replaced my Trimark latch in April 2019 to the tune of $140 (it still had the pot metal bolt) and it started acting up today. (The latch was binding and wouldn't retract all the way or extend all the way.) When I disassembled it to see what was going on, I noticed that the pot metal bolt has a hairline crack on the bottom section of the slotted area. There was a small piece of plastic that apparently wedged itself between the bolt and the surrounding mechanism. I cleared that out of the way and the assembly seems to be working OK, for now.
I just ordered the replacement piece from your link and I'm going to baby the latch until it comes in. Oh...and I also made sure I can get in through the driver's door in case the bolt cracks when we exit the rig.
Anyway, thank you for posting that link. :)
