Yoke not fitting into tranny problem solved!!!

The answer to the problem was that an 'incorrect' bushing was placed in the tailshaft housing. Fred glazier from Glazier's mustang gave me the tool I needed to remove the bushing and to install a new one. The new bushing fit perfectly over the yoke. When I removed the old bushing, it absolutely did not fit over the yoke. So the rebuilders screwed up by putting the wrong bushing in. Now the yoke goes on. Thanks to everyone who helped.
Glazier's also made good on giving me a new oil pump shaft. The rebuilders screwed that up by re-using my old shaft, and not having the 'stop' on it. Still don't know how it got into the oil pan.
So what's the moral, don't send your stuff out to be rebuilt?
I don't know.
But I do want to thank everyone again, and also to Glazier's for 'taking care' of me by providing the parts I needed without any argument.
Now I can try again to get the car started and out of the garage this weekend. Hopefully the next post you see will be one of a successful moving of the car under it's own power!
