That is the easy part. Drop it in first, count the input vs. output turns. Do the same in 6th. You'll know what the ratio is real fast. Without a tag, that is the only way to do it.

My guess is it will have a .5 sixth gear ratio, which gives it a 2.66 first according to the chart, since just about all the T56's with that input output spline count have that ratio.
