Hi everyone, new guy here, love '67 - '72 trucks. So anyway, I bought a '72 shop manual to help me relace the really screwed up carb on my newly-acquired '72 half-ton. The shop manual shows a lot of stuff related to emission control (anti-deiseling solenoid, vacuum advance control circuit switch on tranny, etc, etc), none of which exists on my truck. Were there California & non-California versions of this truck, or do I have a truck with mixed-year components? Here in New Hampshire, emission equipment rules seem to have been sorta elastic with older trucks, but the state is on the verge of tightening the enforcement, & the rule is whatever came on the truck must still be there. Are your eyes glazing over yet? Sorry.
