The GM 10-bolt was only used in Rodeos.

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!

For more clarification - this here is an Isuzu 10-bolt with Tera 5.38s and an ARB installed. The arrows point to 3 of the 10 bolts that hold the ring gear in place.

PS I'll leave the 1000 words to Smiley, I like pictures!!

Ahh ok thanks for the info and nice pic! <img src="/forums/images/graemlins/kewl.gif" alt="" />

so maybe they used it during the transition? Or maybe someone who owned his rig before him swapped one in after some breakage or an accident? I mean, you gotta get a rear, you don't see any troopers at the junkyard, you see an isuzu rodeo, grab that rear, all bolts up, bada-bing.

Eh, who knows.
