Driveshaft won't fit in tail housing

Driveshaft won't fit in tail housing I just installed my LQ9/T56 combo into my '67 Camaro last week. Today I was going to install my old driveshaft to measure to have it shortened, and I couldn't even get it started. As soon as it got past the rubber seal, it stopped. I cleaned both parts with brake cleaner and lubed them both up before trying to install the driveshaft.
The driveshaft has less than 1000 easy miles on it and was mated to a 27 spline Saginaw transmission. I removed the driveshaft from the Saginaw and it slid out without any problems. The GTO T56 came out of a running/driving car, so I thought this would just slide right in. Unfortunately I did not test it when it was out of the car. The spines on the output shaft look straight without any obvious burrs, and the splines on the slip yoke look clean as well. Any thoughts?
Here are pics of the output shaft and the slip yoke:

Take a look at the bushing that is in the tailshaft to make sure it didn't get bent or offset somehow, the second thing I would do is get some emery cloth (really fine sandpaper basically) and polish the yoke on the driveshaft really really well. When I went to install a new driveshaft in my t56 I had to polish the yoke quite a bit to get it to fit without having to force it.

To change out the shifter cup assembly you will need the trans in a vertical position with input shaft down. You will either need a hole cut in a bench or it supported in some way in this position, if you don't the 5-6 gear assembly will fall out of the bearing cups when you remove the tail housing. You may not have to remove the housing the whole way but it will be easier to scrape the rtv and apply new. But before you remove the tail housing, take the two torx head screws out that hold the detent plate under the shifter cup. It has to slide out with it and be careful to not loose the detent ball when you pull the housing up.
Installing I have found that holding the detent spring and ball in with a tie wrap around it and then cut it once installed. It has to go together at the same time and an extra pair of hands is helpful but not necessary.

I just installed the engine/trans so I haven't filled it with fluid, there's no console or shifter, so it should be pretty easy. I'm just worried about that 5/6 gear assembly, do you know if that's really an issue?
