OK, now I am really cornfused. First let me say that the hubs that are on my '64 K10 Suburban are Warn hubs and have no external bolts. I looked at the MMK-423 hub at Summit that LONGBOX55 recommended, and they have 6 external bolts. So, I don't think they will work. Milemarker has the Selectro model #11001-01, that they list as for a 60-68 1/2 ton pickup. These hubs have internal bolts. I was told that the chassis parts on a 1/2 ton pickup and 1/2 ton Suburban were the same.
Fireballv8, have you tried the Selectro #11001-01?
sub65- do you know about brake parts? Will drums, brake shoes, wheel cylinders that fit a 1/2 ton pickup work on a 1/2 'Burb?
