You should have gotten the whole changeover off that car. All the pump parts should mount the same on your car. You'll want to get a different crank pulley so you don't have to use that goofy rubberized one the A/C cars had. Just get the 2 groove one for a car without air along with the matching water pump pulley. You'll also have to either change the column or just the center shaft w/coupler from a '63-6 A-body P/S car. Keep in mind that the column floor plates are different between years so you'll have to strip down the column to change it anyway.
