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.

Does the new pulley have the same shaft size as the pump? The reason I ask is if the pulley bore is smaller than the pump shaft, you can bore the hole in the pulley so it is .001 - .002 smaller than the shaft, heat the pulley in the oven and install it on the pump shaft. If this is possible, you don't need a keyway. Just a thought....
