Steering Colum to Power Steering Link

[ChallengerVert]

Does anyone know why the steering colum and steering box will not fully seat in place?  I have a 71 Challenger with a 440.  I have new hoses, another mechanism and power steering colum (just in case) and a new box seal kit, but can not understand why the steering box will not go together.  The car has been this way since I bought it.  It drives fine but does have a little play in the wheel. 

Any ideas?

there is a small pin in the housing that could be blocking it right near the top of the coupler

Thanks Chryco!!!  Do you know if I need to take the colum out to push in?

I doubt it , you should be able to pry it out of the way
