1973 emissions equipment

AIR system, EGR, charcoal cannister, PCV to carb. No cats. But (at least here in Colorado, anyway) it is not required to be in place. It was California equipment only (at least the AIR & EGR), but was installed on all cars. Therefore (I repeat, at least here in Colorado) it was not illegal for me to remove the AIR & EGR.

PS: Engine was built to run on unleaded gas, but with no cats could run leaded. The gas filler has no restrictor for the unleaded nozzle.
