check that there is a multiport fitting behind the carb on the manifold that will supply full vacuume. Power breaks may or may not be hooked up to it.. Your choice it to connect to it, or there may be a vacuume out tube on the front left corner of the carb. Advance should get full vacuume and not ported.
If niether of these exist. go to your local auto store and ask for a manifold vacuume port adapter. You'll likely find it on the performance isle.
