hey all, to get your dual front brakes on your older 750, get the whole front end off of a 78F or GL1000. The wing front is wider and stronger, but you have to use the 750 bearings (tapered rollers). There is the issue with the guages, I made two small 1 1/4x3/4 tabs with corresponding holes to mount my 750 guages to the wing's top plate. When everything is on and mounted, you can't tell. The dyna ignition install was a breeze, the bike runs a hell of a lot better.
