Pete Markel That suggestion of 383 sounds good ,the added torque would help you. The brownie is an in-line added 3-speed that would give you 12 ratio's. Think I would try the 383,then you could find a bolt-in 2 speed axle that wouldn't be too much trouble to put in. Give you 8 speeds forward and 2 in reverse LOL .Seriously you will use your 2-speed in reverse if you need to back very far. good luck.
