where can we obtain an add-on crank pulley for the ac compressor?

Those are in demand and not on the market very often. You might place a wanted ad here and maybe at PAC and AACA forums and hope to get lucky that someone has a parts car or saved one off an original AC equipped car. Be prepared to pay if the past examples are any indication. Some have even resorted to coming up with ingenious ways of mounting the compressor to be able to use the single crank slot to drive the entire engine.

Since you have a 51, it should not have power steering so might be easier to find a power steering drive pulley and use that. It is a bit larger diameter than the factory AC pulley but the modern Sanden compressor should be able to handle the extra RPMs. I don't remember if the 51 vibration damper was drilled or machined for the additional PS pulley so might need to get the entire damper assy and PS pulley off a 53 or 54.

thanks for the info Howard.
