I finally managed to dig out the old one (lotsa #@#%$#[email protected] and force) with a pair of good pliers. It finally screwed out. However, the plastic locking nut is now loose inside the bumper. Now, how does one get it back together? There is only a little hole and the locking screw has to stay inside the bumper.
Anyone done this before? It looks like the bumper has to be pulled to do it right. Thanks for any tricks and thoughts. I'll be checking back on my breaks from wrestling with this thing. If there is interest, I will post summary of the match.
