I have a Superior Axle catalog that shows the '70-'81 4WD 12-bolt axleshaft being 1/16" shorter than the '70-'81 2WD 12-bolt axleshaft. Seems like it would work... 4WD axles around here are easy to find, and pretty cheap (or free!).

I have a buddy who is using a 12-bolt 4WD version for mock-up on a project. I'll check it with a 2WD shaft next time he takes it apart.
