I want to do a 13" brake conversion on my 71 Elky.I have reviewed several posts and all the info I can find. I tried to open the info on David Pozzi's website, but each time I click on the 13" conversion link it states "page not found". The only info I can find is one where the rotors are cut off a hub to make an appropriate hub. I dont have a milling machine. Are there any other hubs that will work on this conversion. Any way to get the info from Pozzi's page, or any other links? I am only interested in 13" brakes. Thanks, Scott!
