Steering coupler not going on

Thanks Cley for your response. Yeah, I thought the same thing, so I separated it again (what little I had on there anyway). The splines on the coupler and on the input shaft showed no signs of misalignment. I ended up taking the steering column out completely, and removing the coupler from the steering column. This made it easier to tap the coupler onto the shaft. Typing this makes it sound easier thean it was. I tapped and wiggled the coupler for a straight hour, but it finally went on. Two comments; one from FABO and one from FBBO were to just keep tapping on it, and it will go. Both eluded to the fact that it might take awhile, and it did. Happy ending!
