Yup, I tried too. I was told that the polymer one isn't necessary and that the metal one is better. I doubt the design was changed over to the polymer style if they didn't feel it was better at keeping the latch from rattling.
Till this day my carrier latch rattles. The only way to get it to stop rattling is the have the carrier make contact with my tailgate at 7-8 inches out but that binds my tailgate pushing it up. I'm sure that will eventually lead to factory tailgate latch breaking or the hinges binding or even worse the sheet metal warping. I'm no expert but those are just my thoughts.
