PO removed the smog pump, but I don't know what else I can get rid of to clean up under the hood. It's a '75, and no vacuum line to the distributor, but I don't know what else most of this does that's all vacuum lined to the carb. I've tried searching and found diagrams, but I still don't know what I need to leave and what can go. There's still an EGR light under the dash with some wires to it as well. I don't think I need this do I? Anyone with pics of their setup would help...
