Lets start over again I see where I may have been confusing.
there are 18 splines on the front shaft and 30 splines on the rear. I marked the spline at the top on both the front and rear.
So with the tranny in 1st gear I rotated the front shaft 1 revolution (18 splines) the rear shaft only turned 12 splines
30/12=2.5 to 1.0
2nd gear one revolution (18 splines) the rear shaft only turned 17 splines
30/17=1.76 to 1.0
3rd gear one revolution (18 splines) the rear shaft only turned 24 splines
30/24=1.25 to 1.0
4th gear one revolution (18 splines) the rear shaft turned 30 splines
30/30=1.0 to 1.0
a little crude without taking the whole thing apart but accurate enough.
so to break it down,
1st - 2.5 to 1.0 ratio
2nd - 1.76 to 1.0 ratio
3rd - 1.25 to 1.0 ratio
4th - 1.0 to 1.0 ratio
thanks everyone for their input.
