The Vintage air does not use an idler pulley.

oh snap, thanks for the info/pic! so I should be good with my stock single groove?
I'm on the hunt because of what the vintage Air rep told me on the phone, but based on your setup he's wrong... I don't doubt you at all, the conflict is just a bit confusing. I'm immediately pretty disappointed if they're giving me incorrect instruction right out of the gate.
the 2 groove WP pulley available on most sites is manufactured by V.A. so maybe he's just trying to sell me more..?

what the rep told me was "you need to swap your current 2 groove crank pulley for a 4 Groove one, and then swap the single groove water pump pulley for a 2 groove one that would have come on an AC car." (I have already acquired a 4 Groove crank one to use). he then said, "you'll still only use 2 belts, no third is needed. one belt will be using the 2nd crank pulley groove away from the block and go around the crank, ac compressor, and alternator. the second belt will use the 4th crank pulley groove away from the block and go around crank, power steering, and water pump."
so it immediately made sense to me that if the WP needs to align with the 4th crank groove (and the power steering that is currently on my 2nd crank groove away from the block) then it probably needs to be in the second, additional WP pulley groove.
I attached pics of my current setup
thoughts? looks like you've been through this installation before and you're first hand experience is already enlightening.
thanks!
