crankshaft pulley problem

[8door]

Hope I don't have a problem posting on this site. I posted on engine drivetrain and only 4 guys are looking.
Any way what I'm running into is the crankshaft pulley availability. I'm adding A/C to a 350 crate. The change to a 2 groove water pump pulley is easy,but the crank presents the problem.
Starting from balancer forward I need three grooves
1. Water pump/alternator
2.A/C
3 position must be blank
4 power steering pump
So I thought I could get a 2 groove crank pulley and ad the cast power steering pulley I now have.( see photo)
No luck at Summit could order but not guaranteed to fit.
Napa nothing my local hotrod shop nothing.
Any body got any ideas?
