Hi; I have a 2000 Grand Prix GTP. I had to replace the A/C compressor, which I did; but I had to remove the bumper. I notice that there is a white plastic hook on both fenders, a bumper support or fastener of some kind (don't know what to call it) but when the bumper in put back on, this latch goes through holes in the bumper, and the bumper is slid forward and hooks onto the fender with this support I'm talking about. Driver's side one is busted, and I'm trying to figure out what it's called and where to get one? Thanks a lot
