They might have nuts on the back?

Far as I know..they don't rivet plate holders on... look closer if it'* warm enough. Then if the plate holder is good...I know of someone looking for one

I have one off already from my 94 SSEi..........interested?

PM on way to keep this thread on topic.

I have two bolts inside those holes, and I've seen some go in through the bottome of the plate holder also.

mine is definitely riveted on, i was gonna take it off to paitn it white but because fo the rivet and the factt hat i dont have any bolts to put in their place and i didnt fele like going to home depot to get some i havent bothered yet

Well mine was bolted on and I took it off years ago, but if it is riveted on, then it is a simple task to drill out the rivets. If you've never drilled out rivets before, pick a drill size somewhat larger than the through-hole and drill intill the rivet head spins off. That simple.

It'* actually somewhat easier to drill a rivet from the tail end, but you might have access issues behind the bumper.

And lets not forget drilling a rivet in a plastic bumper cover...hmmm heat...plastic. never a good combo.

I agree. I should have written a caveat to the instructions above.
