C4 outputshaft

Does anyone know the major and or minor diameter of the 28 spline output shaft. I need this info to order a new slip yoke. If anyone has a tranny apart or old output shaft they can measure for me.

I have never heard of anyone asking this info to purchase a yoke. I ordered one from Mark Williams years ago and it fit perfectly.

The place that I would/could be getting a new slip yoe from is a distributer of drive line parts for trucks mostly, they go by the specs ie spline count, lenght, u-joint size, major dia. of splines on the output shaft.
So all I need is the outside diameter of the output shaft and I'm off to the races so to speak. Come'on someones got to have a shaft they cane measure for me.
