Wonder if you could carefully sand down the stock switch's face to remove the black part around the AUX # lettering and then put a thick decal over the face, that way the stock lettering doesn't show through.It's on my short list to work on decals to apply to the stock AUX switches.
The page you linked to is selling aftermarket Carling switches that happen to fit in a spot next to the console. There is nothing ford specific about those, nor do they appear to tie into the ford up fitter package that is similar to our AUX switches.
