Suregrip differential (cone type) bearings

[circlepilot]

I'm wanting to change the bearings on the "cone type" sure-grip differential, that I just got for my 8.75 rear end. (489 case) I've been seeing some conflicting part numbers for the bearing cups. (races) Timken LM104912 and LM104911 (the cone bearing is a LM104949) Which bearing race is the right one?

LM104912 is the one you want.
