Got my flip top gas cap. NO fasteners. NO instructions. From BE&A. Nothing but the cap and trim ring. Same as the cheap importer off ebay. SAME EXACT CAP AND RING! Save your money! I'm not very happy. That being said, what hardware do I need? How to mount? I am SERIOUSLY dissapinted in BE&A. For $200 bucks, it should have come complete with directions. KMA! (stands for kiss my a$$) I can't begin to explain how dissapointed I am, and I would NOT recommend them to anyone else. SERIOUSLY? a few cents worth of hardware? For $40 bux more than the imported version that is the same thing, to the nuts, off EBAY?
