A833 O/D gears in an A833 1:1 ?

I'm trying to search my old, dead, worn out memory cells on the extension housings on the GM 833's. For some reason, and this is just a vague thought, the X housings had a cast in "bulge" (big eyelet?) on the back of the housing on the TOP for the tranny mount??????? My memory cells could be recalling a completely different trans all together, too.

One thing for sure. With the aluminum OD extension housing, I've had quite a few of them with the rear yoke bushing completely trashed and spun in the housing, ruining the housing. Always make sure your unit if full of oil (good old 90wt, or in zones like So Cal 80-140 GL-4). I always overfilled my personal transmissions by just a little, maybe a couple of extra squirts, but they were always fresh with new seals.
