model numbers? well, I have a RTLO 16913A early big bearing case eaton and that is the model number. oh, by the way- fifth gear in low range on this gearbox and sixth gear (high range 1st gear position, no split) is the same ratio! so, one can do the splits going from sixth to seventh gear  a bit better when heavy and climbing a grade faster by using that gear- and not loosing any more momentum than necessary~

so, they made several ratio spreads for different motors, I think. that's in response to one other reply that listed the gear reduction ratio's.
