This car did come stock with a vacuum booster and a single T vacuum line. to the booster and PCV nipple.

I could possibly route the vacuum intake straight to the booster, maybe with a check valve and route the pcv valve up to the air filter intake or drill out and tap the intake boss over the #1 carb and install another vacuum fitting to the PCV valve.

I'm not sure what would screw up my PCV system. Seems to work ok as is.
I'm really unsure how a single vacuum fitting would provide LESS vacuum to the booster than a double fitting. Furthermore, if I had a bigger vaccum nipple fitting, the hose would be too small to fit over it, I'd have to have a neck-down at the booster.
