with such a bastardized version of a 727 you have now, IMO your better off either buying a new one, or a known good used one.

oh it an I.S. then yah, it has an early style planet. didn't think the output and tailshafts were that rare, don't early RAMS use the same setup?

The easiest way to see if the output shaft and planet splines match is to mount the front planet only on the shaft and shine a flashlight in from the back side, any mismatch will show on the light shining through the front.

Isn't the difference in the shape of the splines? I thought the early units used a rounded spline and the later ones went with sharper splines.

The difference is in the angle of the individual splines.
The spline included angles are as follows:
'62-'75= 90°
'76-'93= 75°
'94-on= 60°
The spline angles are sometimes expressed as the pressure angle which is half the included angle (45°, 37.5°, 30°)
