Master Cylinder Vaccum Line Need Help

[ohwhatafeelinke30]

Hi i recently put the 3k-b manifold and carbs on my ke30 2dr and discovered there was no bung

for the master cylinder vaccum line in runner 4 like the previous manifold.

 

so will i have to get a bung put in or is there another alternative?

Take the bung out of the previous manifold? Or does it have 2 booster line outlets? If so it might be a good idea to get some sort of connector to connect the 2 together.
