Mark, the one we have does. Well, it did, they were cut off. The Chevelle housing does not have the big inner pinion bearing, or the big carrier bearing saddles. This housing has the big inner pinion bearing and the ears cut off of the top of the center casting, or at least almost all of them are gone. I've seen stock Chevelle and Camaro housings cut for the big carrier bearings, but I've never seen one cut for the big inner pinion bearing. It might have been there on some COPO Chevelles, but those cars were very rare, and I doubt anyone cut one of the housings up like that to fit a Camaro.
