It is that braided steel hose and everything that connects to it, from the intake manifold it connects to the EGR vacuum switch, then the EGR Filter under the intake manifold, then over the the exhaust manifold.  You may have to get creative to plug the hole on the exhaust manifold (some people stick a coin in there) there should be a fitting on the exhaust manifold that converts to a pipe thread and then the hose connects to that, you can get brass caps at home depot that fit that pipe thread, that is what I did and it has held for many years.  On the intake side you can do something similar or buy a block off plate from 02again (recommended) just make sure you seal up the hole on the intake completely, a leak there will cause your car to run like crap..

 

Is that motor out of a later car? I don't remember the 72 having that type of EGR, looks like 74 or later. One way to tell is to get the vin number off the engine (on a flat spot right above the starter) if you can find it, post it here, I'd be interested to see if the engine was swapped for a later one.

I also thought that that intake manifold fitting only went with thermal reactor cars, and that thermal reactors came in '74 or '75. The thermal reactors, however, disappeared so fast that I haven't seen an installed one first-hand in decades!

That engine came out of a car that was built 5/74 (139 cars after mine was built in the same month) and explains a few things, that engine had EGR but no Thermal Reactor, the good news is that if it has the original exhaust manifold then it is a good one to have after you plug the EGR hole because there was no air pump that model year. also if you have the original distributor then it is a vacuum retard unit which is not optimal, take a picture or post the numbers on the side of the distributor so we know what you have. That engine is fairly easy to desmog it should only take you an hour or so to remove the EGR and cap off all the vacuum ports.
