GT500 Distributor Vacuum Line Routing and Fittings

[mr68shelby]

I am getting ready to install the vacuum tree for the distributor advance in the thermostat housing. 4 speed car. Mine had been removed at some point in its life. Does the vacuum line to the intake manifold attach to the front or rear PCV fitting? The rear PCV fitting on mine has one unused vacuum port. My front fitting has no vacuum ports at all. But I have a spare one that has two vacuum ports on it. Thanks in advance. Mike
