More splines = more strength.

FWIW - Chev 10 bolts are 28 spline, Dana 44's are 30 spline. You can't swap them.

Some front 10 bolts 88and up have 30 spline axles, you say yours is a 3/4ton though. 10bolt or Dana 44 ?
If it is a ten bolt the 28 spline chrome-moly
shafts should be plenty strong, you could swap a 30spline rear 10bolt differential in your front houseing for 30spline shafts, but it sounds like more trouble than its worth.

Dana 44s came with 28 or 30 spline shafts, if you are upgrading you might as well go with the 30 spline.
