Or, switch the formula around to find the ratios needed to attain desired ground speed. Then look for trannies and/or axles that give that ratio. Maybe both an AA four speed and a "dual high" under drive will get 'er slowed down.
Yeah, unfortunately that ship has already left the dock. I think if I can find and install a four speed I will be good.
