The other one is for accesories, or not used and plugged. Did you look at that GM starter shim kit that inlinetube sells for $8.00? It's a great kit.

Freethinker is correct. Your PCV line goes to both fittings. There is a special nylon "Tee" that is unique to your car. The vendors have them ...it's not cheap for what it is. The '67 has a "dual plane" intake and you get PCV vacuum from both ports.
