I have a 657, I know it does not belong in this car, the yolk has a 1 1/8 u-joint. Will this yolk fit on a 741 or a 489? Or do both of those units come with a 1 1/8 u-joint also?



most 489's use a 29 spline yke , that 657 probably has a 10 spline , 741 can be either depending on when it was built .
