The rivets hold the part securely so the gaps are kept even. You have to bend the radiator shroud back quite a bit, but I was able to push the center of the two recessed retaining pins in with a small screwdriver to loosen them, then used small needle nose pliers wrapped in painter's tape to pull them out. The clips on the underside were tricky, for sure, and required some patience. I used a small screwdriver wrapped in tape to push up on the clip, pushed the trim piece in slightly, then pulled out. It would be easier with an extra set of hands. I think it is still easier than removing the whole grille, which includes drilling out even more rivets, disconnecting the electrics and possibly scratching or otherwise damaging an incredibly expensive part. Good luck!Thanks so much for this information! Mine just got damaged by a flying object and I need to replace mine. Sadly Revmoto doesn't do 46V (soul red) or I might have ordered the part even at that crazy $400 price tag as I'm sure the body shop will charge as much. I'm going to remove mine just to see how it's done so they don't try to stick me for removing the whole front end (which I've done before). I'm gonna replace those rivets with regular push in retention pins to see if that will work. I don't even know why they use rivets. I have all the top fasteners off and two underneath and this part is as secure as Fort Knox.
I just figured out where the ones on the end over the headlights are. You really have to pull up on the radiator shroud plastic piece to see it and shove a small flashlight down there. They are upside down so they are easier to push than to get the fastener removal tool onto to pull.
The ones on the underside are tricky. I cannot figure out how to wedge in a flat head and then push up on them while pulling the cover forward to unhook them. You can try using a screwdriver on the side of the angled part to get it to lift a little then put another flat head under it. But I haven't had success with this either. For the four inboard clips you really need to bend back that radiator shroud a lot just to see them. It would be easier to just take the whole front end off I think.
