I didn't think there was any difference between the Eaton limited slip unit's axle shafts versus the standard differential. They both utilize the same axle housing.

FWIW, axle shafts in general may not be as rare or expensive as you think, I snagged a good spare set from a '60 half ton a few months ago for about $50.
