Kelsey Hayes KH SBP Hubs and Caliper to Spindle Bolts.

Check this "very informative" thread for the bolts. They are not the original bolts, but I ordered the exact bolts from Fastenal and they work fine.

You are only going to find the hubs from somebody on this site. There is a listing on eBay right now for hubs, hoses, pads, and the MC, but the price is $350.
