Hello Sledge,
If you are talking about the bottom button on the lower part of the fender.... It will take a LOT of dental floss as I think it is through bolted...

Anyway guys, here is what I just Ordered, a full chrome bolt set EVERYTHING, tranny, primary, rocker boxes, engine, head bolts THE WORKS...
I know I am Old School, but it just gives me the eebie jeebies to look at chrome with cadmium electro bolts... Also, it might be a over the top, but my Top box did not come with the side lower LEDs, red illegal in Oz... As it is it came with little silver horse blinders on the big LED lights, which have now gone missing... heh he.. Anyway, LEDs on Mirrors as well, double band of yellow, can't hurt, and will look good at night... I was thinking of blue neons under the tank for the chrome, but I was told I would be pulled over for sure as they are dead against that, "distraction in traffic" sort of idea...
Gee, I thought that was EXACTLY what I was looking for, distraction standout in traffic..
They got NO SENSE OF HUMOUR ....

Reflector is gone, but here is the Australian version with no side lights on the top box... I am only doing the front mirror lights as I added the LED lights in the windscreen trim... Dig the big rig look...
BIG BLUE now has a respectable 7,500 kms in 14 weeks... This is an old picture, I also have goodies like the locking flod down glove box lids and chrome in the dash and more...
