Kenny W,
If the splines are not the same and both axles are Dana 44 You can just swap the spider gears. Just make sure the carrier is for the gearset You have, as long as there are 2 carriers, one for the gearsets from 2.87/1 up to 3,54/1, pinions ranging from 15 to 13 teeth, and another one for the gearsets equal or higher numerically than 3,73/1( gearsets with 12 - 8 teeth).
4onthefloor,
As far as I know, in the dana44 rear end all spider gears are interchangeable, as long as You're playing with the right gears for the right carrier, one leggers can take all for this use and the limited slip only with limited slips. But the smaller ones and the inner shaft are the very same stuff for all of them.
