1980 C10 Inline6 250 Carb vacuum and brake booster

[larey]

So I saved this 1980 C10 from the salvage yard but it did not have power brakes and was pieced together from the salvage yard. I ordered the CPP brake booster master cylinder combo as it showed to be a bolt on version.....Yeah after about 3 hours of work to take the pedal support out and take off the studs that where there. I am having problems figuring out where I am suppose to hook up the brake booster. After looking at other post I understand it normally goes off the intake so I will keep that open. Besides that I am trying to figure out what on the carb is right and what is wrong. Currently have screws in all types of hoses to eliminate vacuum. What can I just straight cap off and what needs to be hooked up. I also know that I have a shift cable disconnected but it is not long enough to hook up as I think the TH350 came out of a different vehicle.

Thanks for the help in advance.
