Galaxiex, Brent, and Woody's, Thanks for the information and pictures. Woody's, did you just machine a "register" in the 1"spacer so the nut would be below the surface of the spacer? With the 1" spacer, do you think the VCs would clear the master cylinder (manual brakes, 1966 Cyclone)? How about plug access with the spacers? Take the VCs off to get to 7 and 8? Thanks, Chuck (S)
