I got my Chrome Seat Hoops today and went to put them on. I had read up on it before attempting and had no problem getting the old ones off. I had read on one of the posts that the tabs on the bottom may have casting flash on them and need to be removed. Sure enough the two tabs sticking down had a U shaped piece on the bottom connecting the two tabs to each other. I cut the U portion off so the tab matched my old one. I went to push it on but it would not go on. I pulled it back up and looked and there was also a piece of casting flashing in the center of the top of the hoop under side. I simply bent it back and fourth and it snapped right off. I then pushed it straight down and it snapped into place. They really look good compared to the old satin ones.
