All my Studes are 44s, Not sure but I think the smaller one they used was a 36. Ford station wagons used 44s in the '50s and so did the early T-Birds. A lot of the carriers and ring and pinions sets will interchange. The Studebaker versions used tapered axles with keys until the last year or so of production. Some postal jeeps used a very narrow 44. It all confuses me.
