So I found a king pin d60 in a u pull it yard that's in a 87-91 crew cab. It looks like its in decent shape but its under the truck still with no wheels on it and no locking hubs. What I'm wondering is if the hubs and rotors from my d50 will bolt on? I'm worried the wheel bearings are rusty and mine are all new. Also what about the ring and pinion? Its the right ratio but I won't know if its any good till I open it up.
