GM made hundreds of variations on this particular carb design, so it's unlikely you would get an identical one on exchange anyways. Often, other variations will work okay, but it's best to stick with the one your car came with.

Noticed something while under the hood. According to a diagram of my carburetor, the "rear vacuum break diaphragm" seems to be disconnected from the hose. I didn't do that so I don't know how long it may have been like this. Could this be a cause of the shut offs that seem to come out of nowhere?

thank you

That looks like an EGR valve..

As much rust and fuel leakage as I see on the outside of that beast, I'd be willing to be the internals of that thing are gummed up bad and the gaskets are probably not much better.
