Gotcha. One final question: If the case determines what bearing size you need, then the diff/locker should work with any bearing size, correct? When I bought my Truetrac, all I supplied to the rep at Eaton was my center section and size (Ford 9") and # of splines (31). He never asked what bearing size I had which is why I am confused (Doesn't take much, I know...).
Thanks for the help everyone!!!
