It's an engineering question

The answer dictates which Optimill Moto-Lita steering wheel quick release hub I buy for Monty, they are offered in 36 or 48 spline versions.
Without stripping the car down and counting, my research seems to suggest I need the 36 spline model, so that would make it Optimill's part number
ORP37-36.
I just thought I sense check this with the collective Talk Morgan brain before pulling the trigger.
ANYONE
