I have EPC, which is a toyota parts catalog for windows. It allows me to type in you VIN and it will give the corresponding parts as well as a bit of information like carb or efi, extended cab or reg cab, etc. As far as the gears go, the only thing that I see that looks like a ratio is 41:10 for front and rear axle final gears in the parts lookup. If there's anything else, let me know, I will see if I can find it.
