This is similar to what I have, maybe it is off a motorhome but I know for sure I got one like this with three groves off a Mopar... CRANK PULLEY MOPAR DODGE PLYMOUTH MAPCO C-77 FOR AIR CONDITIONING SINGLE GROOVE | eBay

I bet MAPCO might have been the aftermarket company that handled add on air for Mopars. The only A/C pulleys I've ever seen factory for the slant 6 bolted onto the balancer from the back. But like I said, I ain't seed it all. lol That's why I tagged @Charrlie_S. He's the slant man.
