Has anyone had to bend the bottom bracket, of the Muth mirror, the one were the under the housing screw goes in ? I have the top brackets in and all the way up but the bottom metal screw bracket will not slide in and seat so that I can instal the screw. The box says for F6B and it looks like if I bent it up a little or dremeld a little bit out of the plasic housing it goes into that it would work. The original go's in and out likity split. Ist pic,muth w/metal screw mount will not slide into main housing mount, pic #2 as stock mirrorr plasic mount does.
