The 2 another questiona are:
1. The carburaters have no fuel return line?
No, not on almost all engines with carburetors. Fuel return lines are more common on fuel injected engines.

2. What is this? Do the Edelbrock need this vacuum part?
Vacuum reservoir. Mostly used to dampen sudden changes in vacuum due rapid drastic changes in throttle position. Usually connected to the vacuum amplifier. Whether you need it or not depends how your engine is configured.
You'd need to talk to Mopar engineer, who thoroughly understands the older systems, for a definitive answer. (Even the most experienced Mopar mechanic probably wouldn't know for sure.)
The shadetree mechanic approach is to disconnect and plug the hose. Then see what happens in terms of engine performance, fuel consumption, and so forth. Disconnecting and plugging the hose won't hurt the engine. Doing so may make the engine run worse ... or may make it run better ... or there may be no discernible change.
Finally, carburetors create vacuum but don't use or rely on external vacuum systems. (There may be exceptions but they're few and far between.)
For nitpicker who may be inclined to comment: True, it's pistons that actually create vacuum. The carburetor (or throttle body) throttle plate merely modifies the amount of vacuum.
