Am I blind?! Vacuum fitting ports

[jkocr2]

I'm not seeing any.. And my intake manifolds don't have any barbs on them either...

No, you're not blind. They didn't come along until the '76-'77 carb set. If you did have them, they would be in those holes just above the cable arms in your 2nd and 3rd pics.

I believe in picture 3 , between your thumb and finger there is an open port---it should have a block-off screw in it---this is where you need to place a suitable threaded nipple---when not syncing the carbs place a cap on it---hope this helps--- tim

I stand corrected by 5twins--- tim

Thanks for the clarification, I was losing my mind hahaha
