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

Not trying to be argumentative, but the roll pin is what holds the coupler to the splined steering gear output shaft.

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 :)
