57 Ford R 11 Overdrive Yoke

[54 Rancher]

I wanted to know if the Standard Three Speed ( T85 ) transmission has the same output spline as the R 11 Overdrive.  I am looking for the Slip Yoke for my unit. The output shaft is  1.375 with sixteen splines.  I assume the Yoke OD is  1.625.  Appreciate any light shed on this with alternate suggestions or if anyone has one.  
Thanks is advance,
Richard

I can't be a 100% sure but I think they are different, A friend of mine is restoring a 57 T-Bird that was 3 speed and he bought a complete O/D set up from me and made it a point to be sure it came with the O/D trans yoke.
