Kimer, before getting too worked up over the fianl drive ratio in the trans, there's and EASY way to figure out what you have by just veiwing throught the trans fillplug hole.

All you need is brake Kleen, a flashlight, a paint stick. Remove the fillplug near the driver's side axle, spray with brake Kleen so the paint stick sticks, mark a tooth, while turning an axle you count teeth. Then you just match up your findings with the chart, below... check out this perfect link for the details, it is right up your alley (I cut-n-pasted from that link) It will also help you find another trans.

Ratio # of teeth on crown wheel
3.52:1 74teeth
3.79:1 72teeth
3.95:1 77teeth
4.10:1 78teeth
4.39:1 79teeth
