slip yoke problem / TF 727

Marty, I will need to get special tools to measure the yoke, but I will try to get those numbers. I just finished measuring a 727 spline and found the following: Major= 1.277
Minor= 1.191
The major is obviously .002 larger than than measurement on my 833, but the minor is.018 larger than mine, Yikes! This only serves to confirm the tolerance differences between shafts. Incidently, my yoke fits beautifully snug on the 727, but brutally sloppy on my 833. The difference in Major and Minor tells the tale. There is no mystery here, Michaels fitment issue is likely due to tolerance dysfunction with the shaft and the yoke.
