Crank Shaft Pully help

[lts70]

I am installing a vintage air A/C kit in my truck and need a three grove crank shaft pulley for my 327 that has a short water pump and power steering. I have looked at every junk yard in my area with no luck. I need the one that has three groves right off of the balancer with no spaces in between the groves to match up with my water pump pulley I already have and my existing Power steering and alternator. I think I just need a 2 grove as I think I still use the first grove from my two grove set up (they split apart).

Does any one know where I can get this pulley? Or even have a part number? I am tired of looking at junk yards and would like to get my A/C going before the summer is over.

Thanks for any help in advance, you guys
