Brake Booster Help

I just got a brake booster off a board member and Ive got a pretty good handle on how to install it. But I had one question: where does the vacume hook up? I have a stock 307 that originally had manual brakes.

thanks!

It should hook up to FULL Manifold vacuum, either a port on the manifold itself or to a port on the base of the carb.

There is a plug in the top of the manifold behind the carb - would this be a full vacuum?

Yes, just take the plug out and get a fitting to put in there to allow you hook the vacuum hose up to. Make sure you use some form of thread sealer whether thread tape or the liquid type.
