I have finished developing a repair for the N65/F65 that so commonly has a broken plastic latch. The test camera I purchased had a intact latch but it was cracked halfway through. It eventually gave up the ghost between the time I took dimensions and the time the parts came back from my machinist.
Since the area is so very small, I had to end up going with a screw to secure the metal latch to the back. It does make installation a little more fiddly but I did the repair in 10 minutes; and that is with taking photos along the way. The latch is made of 304SS that has been bead blasted to get a nice satin finish. I also will include a stainless #0 Philips screw. The latch does get glued but that is more for positioning than permanent application.
