The OEM 741 carrier I have has an 1 1/4" pinion nut versus the 1 1/8" nut on the 742. According to the Doc Diff the larger nut has the fine spline and the 742 that I have that is rebuilt and ready to install has the course spline pinion.
Hate to say it but did you ever think Cass could be wrong? Find me a set of gears for a 741 or 742 with the 31 spline...... I'll wait...
