Someone has disconnected or plugged most of your smog stuff already. If you are asking about that round metal thing in the left part of the picture below, that looks like part of the thermactor or air pump system. It goes into the exhaust manifold correct?
If you are asking about something else, you need a better picture like the one below.
I'm a little puzzled by the routing of the PCV hose. This is the hose from top of the passenger side valve cover, near the back. In stock configuration, the PCV valve plugs into a grommet in the valve cover. The hose then runs to the base of the carb. See the picture in post #2 above for comparison. With the engine running, fresh air is routed into the crankcase via the driver's side valve cover (yours has a chrome breather vent), through the crankcase, and out via the PCV valve to the base of the carb. Fumes from the crankcase are drawn into the intake manifold to be burned off in exhaust. This is a VERY beneficial system that long predates any emissions controls, and helps prolong engine life by extracting moisture and harmful fumes from the crankcase.
On your engine, the hose sticks straight up and there appears to be no valve. The valve is very important, as it automatically shuts off (or reduces) airflow at idle. If plumbed directly without a valve, it's basically a giant vacuum leak at all times. Was this something a previous owner did? Did he leave you his genuine faux bronze belt buckle from the "Rip out all that pollution crap" club?
correct I bought this truck exactly how you see it. So it’s been a nightmare trying to figure it all out. I will take a look at the pub hose when I get off work. Thank you

That’s good. Is there a valve somewhere in the line? Typically it’s where the hose is connected to the valve cover. Hard to tell from the picture, but that looks like a plain grommet with no valve, connected directly to the hose.
Yep, that's the connection which has me puzzled. What's inside? Is is just an open fitting? Many PCV valves have a 90 degree elbow like this example. The silver base plugs into the big grommet in the valve cover.
See the picture in post #2 above for a typical installation. The part you have looks to be painted the same gray as the valve cover, so I'm thoroughly confused.
I'll have to research a bit more tomorrow when I have a little more time. No idea if that grommet is the right size, but that's the correct general idea.
The 47032 elbow? I think that is just a generic barbed elbow, hollow on the inside. It does not appear to be valve/elbow combo, like the one in post #13 above.
Back to what is currently installed. Is that just an open fitting? I'm still puzzled by the straight fitting painted gray. Makes me wonder if the valve covers (or maybe the entire engine) came from something like a marine or industrial application.
