Power Steering Pump Pulley not lining up

Usually you'll need a matched set of pulleys and brackets off the same engine. Mixing and matching from several different years just doesn't work. I definately don't recommend any shimming with washers....that's just asking for a broken pulley. With 4different pumps, various engine sizes, A/C and no A/C, cast iron and aluminum water pumps, there are dozens of combinations. If you have a '68 engine with the '70 up water pump/timing cover, you've already got problems to overcome. What is the engine in? Which radiator are you using?
