Yea totally agree with the guys above. Thanks Joe totally forgot it was open. (all min are posi so i hardly think that way)
I think its a adapter or go the speedbox route is the fastest and easiest way to get there.
Because like the other guys have posted. The driven/drive gears are really limited for that transmission.
And the adapters need ratios to match up all of the above so its a lot of ratio, on ratio, on ratio calculations.
But will let the original poster decide which route he wants to go.
