A833OD inspection results... thoughts?

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.
