Rules required an open differential, and we've got 31 spline Moser axles. Where can I find a 31 spline open diff. for a Ford 9"? Seems like everything has 28 splines. Did the 31s come stock on anything?

2wd late 70's and early 80's F-100, F-150, and Econoline vans had 31 splines. I think most of them came with a 3.00 gear though.

2WD Ford pickups had 28 splines and the 4WD trucks had 31 splines.

o5racer is correct. I just pulled a rear-end out of a '78 F-150 2wd yesterday and it had 28 spline axles.
