I received and installed my original Sunrider in July of 2020. I noticed in November 2020 that my passenger side Z-clip was broken. The top was replaced under warranty and the new one has been on the truck since December 2020. This morning when I arrived at work, as I was closing the top, I heard a loud 'POP'. Of course I immediately though of the Z-clip and sure enough it has broken again. So disappointing. I guess I'll have to try to come up with some sort of DIY fix.
