Emissions on my Slant

Hello all. I’m working on my first 1970s Mopar A body. I’ve noticed while going through the engine bay that half of the emissions lines are not hooked up. Only one line to the canister at the front of the engine bay, a yellow sensor with 2 vacuum ports in the valve cover isn’t hooked up, etc. Wanted to know if I needed these items connected or if they can be removed from the car entirely. It’s a 1976 Scamp with the 225 slant. Here are a few pictures of what I’ve noticed…pardon the mess in the engine bay, I’ve been prepping to pull the engine for a rebuild.
