Unfortunately, Bruce is no longer with us. He lost his cancer battle back in 2011. He was a wealth of information and one cool dude and a good local friend to me and online friend to a lot of people. He is sorely missed. That said, the 9" hubs will not work with disc brakes, at least I believe that was your question.
Wow , I didn't realize his posts were from that long ago! Very sorry to hear about Bruce, though. My sincere condolences to his family and friends. So the missing pieces then , are the original SBP disc front hubs
