I have been told by several people over the years that the ring and pinion gears from a Dana 44 axle can be made to fit into the older Dana 41 housing, as used on M5 and early 2R5 trucks. To get a ratio less than about 4.54 needs a different carrier, too.
How do we sign you up to test this theory so that something between 3.73 and 4.11 could be put into a Dana 41 using "modern" gears? I do have a 3.90 ring, pinion, and carrier from a Ford F1 truck that also used the Dana 41 axle, thanks to Dick Eichof, but those parts are as rare as the Studebaker ones. It would be good to have a documented example of such a conversion. I'd be happy to loan them to you to use for finding a match.
