Just wanted to revisit this quick... I just mounted an '04 Axiom fog switch in the fuzzy bezel with no problem. Did take several minutes of Dremel work however, and since it's a tight fit the back of the bezel looks like it went through a meat grinder. On the other hand the switch sits perfectly flush with the blank/tailgate switches, does not move when depressed, and you can't see any of the Dremel carnage from the front.
I found that you need to cut the corner piece but also grind down the plastic "lip" that adjoins the corner. Shaving that piece down just a hair (maybe 1 mm) allows the metal retaining clip to slide all the way through and lock.
So for anybody worried about making these switches fit, don't be!
