Mike,
I think you are looking for the 3053A from a 2.5 ton military with multifuel. It has about 0.80 overdrive ratio. It also does not have provisions for a spedo cable or a parking brake.
I would not pay over about $250 for a really good one. They are so plentifull in the surplus market that they can be found at a good price. A friend of mine got one for $20, but he is lucky. I have a lead on one around here for about $200, but I have not seen it yet, I can dig up the phone number if you want?
