I am doing a front disc conversion using a Wilwood kit on a '68 Cuda. Ran into the following problem: the diameter of the snout on the Wilwood hub is wider than the center opening on my wheels. My wheels are rallyes, not sure what year or make they came off originally but they fit the original hub snout. Wilwood tech support has basicaly told me too bad. I have the 10" kit and Wilwood is telling me even the hub they use with the 9" kit is too big for my wheels. Has anyone encountered this problem? And what are my potential solutions. I guess I could get new wheels, but I like the wheels I have and I'm not looking to drop another grand on wheels and tires. I am thinking about a wheel spacer/adapter, but don't know much about them.
