I agree that it's probably a Piper part. I found a lot of similar used items online, but people are asking $300-$400 for them. That's not going to happen. My plan is to take the latch off at a convenient time and manufacture an aluminum part to replace the plastic one. I have three latches on my door, top (inside/outside), shoulder level (inside only), and the door handle (inside/outside). The broken top latch works fine from the inside. I just can't latch it from the outside, so it's going to stay there for a while.
