If going into a 73-78 these differences would have to be addressed. This column has cruise control & delay wipers which I have been unable to test. Yours must have the delay option as well to be the same. The tilt lever just screws in. The turn signal handle just pushes in (Must line up the little prongs).
The shifter just goes in, and tap the pin. Tilt is tight as well the steering wheel lock works key included.
