Problem is also caused by the original installation of the rivets. As with aluminum rivets the the stem that is held/pulled by the installation tool snaps off when the rivet is fully seated. When I installed my MOPAR winch mount the front bumper crush zone components were also replaced. There are two plastic rivets holding each crush zone plastic cover in place over the fog lights on the ends of the inner bumper. The way I removed the old rivets was to pry them out which destroyed the rivets. I would think that drilling them out would render a similar result. Also be advised that the plastic rivets require their own installation tool as the 'stems' are much larger in diameter than their cousin aluminum rivets. I could not find an adapter for an aluminum rivet 'gun' large enough to accomodate the plastic rivets, hence my previous post about the $14ish Harbour Freight plastic rivet set. All I needed at that time were the removal and installation tools but had to buy the entire set which worked out as now I have rivets as well.
