In this video a 1973 Mustang with a 302 V-8 and automatic transmission is used to show how the distributor vacuum advance, EGR, and automatic transmission modulator are routed from within the engine compartment near the carburetor. The same Mustang with a 302 and manual transmission differs in a few ways. First, the vacuum advance diaphragm is a dual diaphragm design. And, it turns out in the auto tranny calibration a single ported outlet from the carburetor is used for the EGR, tranny modulator, and distributor vacuum advance actuating. For the manual tranny the carb has two separate ports, one for the EGR and the "back side" of the vacuum advance canister on the distributor, and one for the distributor vacuum advance diaphragm's main connection.
