What years of power steering will fit a 64 A body?

Most of the small pitman shaft steering gears will fit the k-member and work.....even B and E-body ones fit, but some look a little different. There were a couple of different mounting bolt diameters too. Fittings can be different depending on application. In '65 on a V8 A-body car, you should have a 5/8" hose size, 45 degree angle, aluminum return line fitting, and a 90 degree pressure hose fitting on the control valve. You'll need to get a P/S center shaft and coupler for your steering column (the rest of the column is the same), a pump and brackets, 2 groove crank pulley, hoses, belt, etc. Get a new lower column seal while you're at it. The factory also had a hose bracket that bolted to the K-member.
