(7th) this vacuum line where my finger is pointing is the brake booster line that attaches to a port coming off the manifold right above the egr... its always been that way

Theres a few corrections you need to make. The port high on the carb that you show in the second pic is your fuel bowl vent and should run to tye charcoal canister. Its actually the light blue vacuum line in the diagram.
The two lines that are Td off the cto need to be Td into the line running to your distributor instead of running to the carb.
The vacuum advance and pcv valve (pic 5) are fine. The pcv breather (pic 4) can be left as is, or you can run a vacuum line to the white capped nipple in pic 10 (this is what i would recommend).

This sounds right I just don't run the vacuum to my distributor since I don't need it now but ill still take some pictures when i get some light hopefully it won't be raining :thumb:

Wow mine is very different...hmm... Here are my pictures. The first one goes from the passenger side of the carb to a t that goes to the CTO and Distributor which I plugged. Then the one down by the driver side is plugged by the brake lines. Then the PCV valve goes to the back of the carb. Then there is one from the electric choke to right below it on the carb. Seems like mine is pretty messed up lol. Oh and I have a push in filter by the screw for the oil so no hose to that one.

In the third picture the missing hose goes to the EGR valve, that I don't use so I have those capped off
