8 3/4" suregrip carrier swap
No go to doctordiff and you Will see there is diferent Bearings set
Biger to smaller pinion
That's why they have different bearing but the sure grip can be used in all the cases
741 smallest
742 medium 1 3/4'' pinion could be the best one there is discussion on that
489 largest 1 7/8 pinion but need a crush sleeve or a sleeve eliminator
Hope that help you
Bob
