Hi Donnie,
Unless I made a mistake in the math, the numbers of teeth on the appropriate gears given in the parts book yields the following for the B:
First gear transmission reduction ratio = 2.5:1
Differential reduction ratio = 5.29:1
Final drive reduction ratio = 4.79:1
This would give an overall reduction ratio of 63.3:1
Perhaps someone else can either confirm or provide other numbers.
Rod
