1 pointThese designs are way over designed and none for an R 10. I have fabricated one for my B3B, with R10 overdrive. It will be on display at Tims BBQ. Parts are at a machine shop now getting "professionalized.
1 pointI apologize in advance to the person I got this from and I will find it and provide them credit at some point. For this one of course it would not work on an r10g1 overdrive, although that is not to say they couldn't make one for that purpose.
