Looking for Duster Power Steering Pump

I am looking for a power steering pump for my 73 Duster 340, Prefer one in nice condition, but as long as it does not leak (with pulley attached) is preferred.I am looking for a Saginaw style with the Egg Shaped tank with the plastic cap, with the dipstick attached to the cap style. Both high pressure and low pressure return fittings are both located on the back side of the tank. If anyone out here has one for sale please P.M. me. Thank You in Advance.
