Gears for MM UB

A

Has anyone ever found an existing combination for faster gearing in the MM UB? Most of the MM parts books do not give a tooth count on the gears and I hate to start tearing down tractors to count teeth.

I'm looking for a 26-28% increase over std 2nd (preferred) or a 7-9% increase over std 3rd.

Custom gears can be made of course but I'm wanting to explore all options before getting out the checkbook.
 
I was at a pull earlier this summer and a gentleman had a U that he had literally put together from parts he had laying around and we got talking about my UB he pointed his trans had a different shift pattern and said he put the fast trans in it.? He must have swapped the whole rear end? I am by no means an expert on MM tractors I just thought I"d pass the info thinking it mite help you
 
yes they have a faster ring and pinion but a slower constant mesh for the 1,3,4 gear. the same for 1st. The moline has a 3 shaft tranny where the farmalls have 2. The front constant mesh in the moline U's are the same in both shift patterns and that is the easier one to change with a custom gear but it will only effect 1 forward gear and reverse.
