ahh.. i see. i didnt have a set of the F's cvd's- just the stock dogbones. in that case, i think it would work fine, as long as the internals are the same. the Yoke cvd's had a smaller pivot inside.
there have been a couple of different ideas on the center shaft... maily getting another of the fixed pulleys and filing a bit. i may try that also. i better get it back together as it was till some parts get here!!!

id switch to the reg 64 pitch... the 04's are terribly noisy with reg pinions, even in stock...
