Here is another calculator that will give you some comparisons of differing speeds, rpm, and gear ratios.

Not to hi-jack your thread, but where else are you guys looking to buy these parts from: 3rd member, axle bearings/seals, axles, and rear disc brake conversions? I got a quote from Dr Diff on a 3.55 tru trac 3rd member, new axle package, green bearings and seals (I know there are mixed feelings about these, but I'm taking his advice and giving them a shot), 10.7" rear brake conversion, E-brake, aluminum master cylinder and proportioning valve.  I haven't looked around too much to compare prices, but I like that I can get it all from Dr Diff and know it will work together.

thanks,
Dave
