I have read threads about guys cleaning up their fwd controls by relocating the brake switch assembly to a pressure activated banjo bolt directly on the brake cylinder. I want to do this mod and found these switches all over the web. I'm looking at goodridge. They offer in many different bolt sizes, 10mm, 12mm, etc. does anyone who has done this mod know the exact part number for the one I need or the correct bolt size so that I can look it up and order the right one? Thanks!!!
