I have my brake check valve vacuum hooked up to a fitting at the back of my RPM Airgap manifold. I am wanting to hook up a PCV in the valve cover (No carb vac port available) Can the fitting in the manifold be shared using a T fitting with the PCV & brake booster? Am wondering if there are issues with vacuum to brake booster sharing vacuum to PCV.

no problem... just make sure your booster line is on a down hill grade to the PCV connection

Manifold vacuum is manifold vacuum whether it is connected to the rear of the carb or the intake. If you have a leak at either place, the entire system will be affected.

In other words, the port that a lot of carbs have in the back of the baseplate that is traditionally-used to connect the PCV is the same as the vacuum hole in the intake. You could connect power brakes, PCV, air conditioning vacuum control, trans modulator, and vacuum advance all to the same port if you really had to and they would still function properly as long as the plumbing was large enough and there were no vacuum leaks.
