Not sure it will work for you but I have a triple crank pulley, pulled from a '72 Chevy 3/4 ton 350, PS & AC. GM pulley, # 3932428 CH, google showed late
60's to early 70's. $50 shipped, if interested I can do pics for you. Would be tomorrow before I can do pics, in the parts stash somewhere. Right now it's snowing, 6 degrees and wind chill of minus 12. I AM SO READY FOR SPRING
