You don't need to use the 500 speedo drive..
You can have the 2nd rotor modified to accept the 750 drive.... not that big of a deal..
Just do that with longer bolts and the wheels ready..
Then check the spacing of the caliper mount and mount it..
The problem with using the early calipers is that one of the hose will be in the front of the caliper and the other will be at the rear..
Using the later calipers is a little neater because that fitting is in the center of the caliper..


Build it the way you want it ..... then learn how to ride it like you own it..
