The little latch bolt can be adjusted up down… and can even jiggle loose. Check the bolt… if your poptop won’t latch, you may need to “loosen” it to bring it down a bit (or tighten it). This is the one with the nut on it. In this photo, the latch bolt is shown only 1/2 way screwed back in here. But it was because it had jiggled loose and was sitting in the latch area. I’ll likely use some thread lock (cause my nut is in the correct position). The adjustment of the nut helps make a tighter/looser seal. When you’ve found the correct “height” of the latch bolt, the nut should be at the top to help secure the bolt.
