I currently have the EGR disconnected
That's fine, don't fret about it. Just leave it disabled unless you have uncontrollable spark knock and can't get rid of it without an ignition timing setting that makes other problems.
My car didn’t have/come with the head mounted vacuum amplifier
It was built with one; that's how the Chrysler EGR systems of that time were designed. Someone took it off.
