The 10-bolt or 12-bolt refers to the number of bolts holding the ring gear onto the carrier.


For clarity:
The number of bolts that are used to describe a differential are located on the INSIDE, where you can't see them. --- It has nothing to do with how many bolts are on the cover.


Also:
When you see the term 'Third member', it means that there is no dif cover at all... The differential comes apart from the other side, and it has a solid face where a dif cover would usually be located. --- With a Third Member, the ring, carrier, and pinion are all mounted together on a single removable unit, and it all comes out from the opposite side.

HTH!
