833 OD slip yoke info.....

yup, 67 and back and aluminum OD. I have a 66 833 and it is 26 and every aluminum OD I have ever had was 26 and every cast OD I have had has been 30.

Well, mine is a truck OD, and it has an aluminum main case with a cast iron tail shaft. I will count the splines tomorrow when I am not so dang tired and report back. Thanks!
