front viper brakes on my duster

Ditto on the hubs question. Is your Duster 73+ with the factory's integral rotor-hub? If I understand, you machined the rotor part off to make a custom hub only, then put a rotor from ??? on it.

Making the custom caliper mounts is great. I hope to do that someday to mount Wilwood calipers I have to my early 10" drum spindles. But, I have no mill yet. Wilwood has those as part of a kit. Maybe I can figure a way to buy just that from them.
