i am trying to build brackets to install a 8 inch dual booster ,on the orginal pedals.seems like all the kits use the 7 inch. i am starting to see why. the extra inch in size ,may be great with 4 wheel disc,but the extra size makes for more offset at pedel linkage. does anyone have posted pictures of their handywork? i think i have it worked out but you may have a better setup. now how the heck to setup clutch linkage or maybe slave system on orginal pedals and 4-speed toploader? weeks of fun... seems i still try the hardest way ,first.
