Does anyone know the OD of the transmission input shaft spline?

I bought the A7550T clutch alignment tool and it is smaller than the spline on the clutch.

My car is a 1928 leatherback with a B motor.

I think it is 1.375 but will have to measure one later this morning to be sure.

Just measured an original and 1.325 is correct. I measured my plastic lineup shaft at 1.285 and it works correctly.
