A833OD with worn output spline

Thanks for the reply guys. I previously changed the bushing with no change, as my first instinct was that the bushing was worn. Using a dial indicator, I measured the same play before and after the bushing swap. After being told the slop was not an issue, I have since had three different driveshafts in it including a new slip yoke, and had the rear gear apart twice. Eventually it all pointed back to the slip yoke. The tranny is out and apart now, and I am measuring the end play with the shaft in a vise, therefore all other parts are no longer a factor. Although I agree there may also be some play in the input shaft, and I do have the parts for a complete rebuild there is no point to putting it back together until I have solved the spline issue. In my comparison with the Saginaw, I had to limit the yoke to 1/2" of spline engagement to get .027 vertical end play. Please don't take it as arrogance on my part, but my interest is really only limited to the fit between the spline, and the slip yoke. If I cannot get a better tolerance on the spline, I will need to devise a new plan.
