I went to swap a 741 case with 3:91 posi and the axles from the 742 were too big to fit the 741 case. I thought they were all the same. Any thoughts?

The racer bought a 35 spline spool and axes for his 8 3/4 You need a set of stock or street axles now to use with the posi Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
