727 yoke wont come out. What's the trick ?

On your example with the nut retained yoke, all you've done is move the slip yoke function to a component in the drive shaft. This may or may not be better LOL

I was also thinking that a Bearing, as apposed to a bushing, would have less friction, causing less heat. should take a bigger load too. All the PRO trans replace bushings with torrington needle bearings and ball support bearings. See PATC trans Low Drag geartrain assy.

Would be nice, but at $795.00 maybe thats why...
