slip yoke problem / TF 727

Measured the spline on both of my mainshafts last night. They show the following:
Original Shaft Major= 1.275
Minor= 1.273
Used Replacement Shaft Major= 1.273
Minor= 1.271

Interesting, a .002 difference between the 2 shafts. Doesn't sound major, but I measured a Muncie shaft, and new slip yoke, and came up with a clearance fit of .003. That corresponds with a beautiful snug fit on the yoke. Although it has become obvious that the Mopar yoke tolerences are all over the place, I am almost positive the shaft spline tolerances are out to lunch also. This being said, at this point we are only talking a couple of thousands of an inch, but that can mean the difference between tapping on with a hammer, or sliding right on.
