This just doesn't look "right" (manual steering)

No worries Ironracer..........There is a tiny pin just at the top opening of the coupler that has to be pushed out in order to remove the "guts" of the joint. The big roll pin you are referring to is at the gear box end of the coupler :)
Yes sir, i actually was talking about the Hardne Solid pin, that is in the end of the shaft itself (holds those two hardened steel, slightly rounded, but square on the "back", where the Square edges are on the Coupler, Bushings almost? if you want to call em that. I'm not sure what Chrysler calls them) that fit inside the coupler...
