When was the stepped torque produced?....Just looked at a 1914 and the swears that it was on their from the factory. Always thought it was late in production.
It seems to me that I find most of them on 26 rear axles.
'24 and later, if I recall correctly from Bruce's book.
I have 2 26's, serial numbers are two weeks apart. One has a steeped torque tube and one does not. I do not know if ether have been replaced.
Absolutely not from the factory on the car you are looking at Warren, unless it is a '26.
They have ro see it print to believe it......He does now,,,
