Belt problem

Would anyone know my water pump pulley lines up great with the power steering pump pulley not really the alternator pulley. Fan/alt belt fit perfectly around the power pump pulley.which is the right side.wrong side it should fit on.fan/alt belt is big around fan/alt side which it should go but doesnt.not the powersteering side. Powersteering belt fits on the alternator side. It's reverse on my 383 do l have the wrong water pump pulley or crank pulley?
