Power steering pump pulley SBC

Just ordered up a nice aluminum power steering pump pulley for my SBC. The pulley I ordered is a keyway fit on the shaft. The pump I have is a press fit pulley by the looks of it since I cant see a key and because when i attempted to remove the old pulley it was on the shaft so tight that it bent the pulley. I am going to replace the power steering pump but need a pump now to match my new pulley and still bolt up with the exsisting bracket. The old pump is off a 1980 Camaro. My question is which power steering pumps were made with a keyway on the shaft? I will need to order one of these pumps as long as it will bolt up and maintain the proper belt alignment.

Thanks,
Keith
