I was looking through american powertrain warehouse catalog. They have an overhaul kit for 1970 - 1980 A833 that specifies a 90mm input and output shaft bearing. My 4 speed is a 1977 volare/aspen box. Without pulling it and measuring the bearing diameter. Did they use 2 different bearings in the O/D boxes, or were all of those 90mm bearings? I dont want to pull the gearbox from the car yet since its installed as part of a mockup, and i would need to put it back in. Maybe that sounds like me being lazy, but i barely have time these days to mess with this project, and am just collecting up parts for when i will have time.

Yes there are a couple of different rear bearings, and I don't recall any of their sizes. 90mm is 3.543 inches and sounds odd to me.
The OD box comes with three different Mopar mainshafts; 2 short ones and one long one. The shorties came in the F-bodies. The slantys got the small diameter output and I think everything else got the bigger ones.
I'm not sure about the small shaft ones, but I am sure that the large shaft boxes take a special width rear bearing.
The front bearings take a special width outer snapring, don't use the one that comes on the new one, the retainer will not seat and then it will leak.
I think the small bearings were 307s and the large ones were 308s; but not just any old 308s. They were a special width as noted.
OK nope, 3.54 is the 308. The 307 is 80mm or 3.14 .

The large shafts take 727 sized yokes while the small shafts take the 904 sized yokes. So you can figure out which bearing to order by which yoke slides into the back.
