this site said otherwise?

Although somewhat rare, there is a version of this diff that came from the factory with 4.88 gears. The carrier (3rd member housing) has a different pinion offset so that the ring gear doesn't need to be as thick. This means that no gears other than the factory 4.88's will fit this particular diff. However, diff cases, commonly called carriers (factory, LSD, lockers, etc.), for the standard V6/Turbo diff should be interchangeable (4cyl and V6/Turbo carriers are NOT interchangeable).
according to that site, i was right... i said the internals of the third, not the third itself, i meant spiders/grears, and that the housings of those wierd 4.88 diffs were no different than a regular housing
