Hey Kelvin -

your dimensions each seem to be 10 inches off, as:

...the Moss catalog shows the following driveshafts:
Banjo axle - 30" standard, 31.125" OD 
Tube rear axle - 31.125" standard, 32" OD, up thru #138400
31.125" all, from #138401 on

Otherwise it matches up -- three different lengths. Though where did you 
get the 1/4 instead of 1/8? I suppose it's just where you measure from...

Also, the expando-joint in the driveshaft can take up any odd fractions, 
as well...
