damaged the rim with a few scratches, had to remove the factory 2 piece tabs because the curmudgeons were trying to dress it up with flimsy eyelet covers that would unscrew and twist. then there is no way to remove the bar without cutting the bars. one got stuck in the impact socket and thus came loose. the rest had to be knocked off with a screwdriver and hammer and then levered off. replaced by these hard tips.
