Lincoln Zephyr gears tooth count ???

Can anyone tell me the tooth count on both 25 tooth and 26 tooth Zephyr gear sets ? Thanks for the help !

 

25= 25/19
26= 26/18

 

Thanks Pete1 !

 

They add up to 44, count the upper, do some math and wa-la. That's if it's still in the trans.

 

They need to add up to 44 . The 25 tooth takes a 19 tooth input gear and the 26 tooth takes a 18 tooth input gear. They both use a 22 tooth Lin. second gear. Fords second gear was 24 tooth.

 

What's the prefer count, 25 or 26?
