I have more trouble with 9 inch gears than any others. I don't know why. I think I would have used the 3.70 gear instead of the 3.75 because the 3.70 is a more popular ratio and produced in higher numbers. They usually work harder to get things right on the high production gears than they do with the low production stuff.
