driveshaft bearing

[calvink at fastermac.net]

I have a spare 90Q driveshaft, and I'm trying to replace the
center support bearing, as the one on this shaft as well as 
the one in my car have torn bushings.  I've marked the 
halves so i can reassemble them in the same alignment, 
removed the bolt at the center u-joint, but still the yoke 
refuses to slide off of the splined shaft. Am I missing 
something?  The online accounts of this job are a little 
vague, and most deal with the 100/200 models which I 
think are slightly different.
