You can remove all that crap but you will have to plug the vacuum ports on the intake manifold. When I did mine I had a box full of wires and crap I took off. There is a wire harness on the pass side firewall all you need to keep out of that is the wires for the windshield wipers. I'm not sure how to to this with a stock carb but it you have a weber it won't be hard. The only vacuum line you need it for the advance on the distributor. Heres a pic of mine
