1964 Buick LeSabre Power brakes

I am switching to power brakes (drum brakes-single reservoir master cylinder) on my1964 lesabre-where do I pick up vacuum for the brake booster with a 300 engine? I only see 1 unused port with maybe a 1/4" plug--but do not know if that is water or vacuum without testing. 1 port feeds the transmission modulator--but don't know if it could be tapped at the manifold to feed it and the brake booster without starving one or the other.

     Any help will be much appreciated.

Any port that screws into an intake runner is a candidate. The 1964 300 motor intake can be a little tricky, since there is a water passage under the carb. The red circles are vacuum ports. I've shown both the 2bbl and 4bbl intakes.

THANK YOU VERY MUCH FOR THE REPLIES. You have answered my question excellently and I have purchased the necessary fittings to install the line.

   I REALLY APPRECIATE THE WONDERFUL PHOTO`S TOO. I thought maybe the port with the square head plug might be a vacuum source--the photo`s confirmed that and that is now MY SOURCE.

      Again---- thank you.
