The Kelsey-Hayes Disk Brake Swap Thread

Correct. Disk hubs are totally different than drum. The rotor bolts to the backside of the hub. The lower ball joints are also different (larger bolt holes).

I have never seen any hubs sold new, either disk or drum (other than 1973+ w/ integral rotor & hub). By "everything else", we assume you have the disk spindles and dust shields. Best source for K-H parts is a member here, Hemi71x (or such). He posts regularly and lives near me. He had a complete K-H setup beautifully refurb'ed for sale a while back. He currently has K-H calipers for sale (Sacramento craigslist, ...). He regularly scours the junkyards within 100 miles to grab those rare desired parts, including control arms and 1973+ disk parts.

As an aside, hubs have never been easy. In 1986, the left hub (9" drums) in my 69 Dart spun a bearing race, ruining it, on a cross-country drive. A shop near Tupelo, MS had junk cars in the rear and pulled a new hub. I didn't know how lucky I was. Same deal w/ the right hub ~1989. A Brake-O in Atlanta put a new drum on the spun hub, said "you can fix that yourself", then charged me big money (why I avoid shops). I went to 3 junkyards and couldn't find an A-body w/ 9" drums, so drove it back 180 mi to Tullahoma, TN like that, and found a hub there. Now, I have spare hubs on hand for all my old Mopars. BTW, 10" drum spindles and hubs are different still.
