I'm trying to run down when the Clean Air Package components were installed on Mopars. Specifically I am trying to find out if my 1967 Hemi 4-spd (Federal) needs the distributor vacuum control valve (code 8-27-335 in the 1967 parts book, PN 2843560). I have found vague references that only the California Hemi cars had them prior to 1968 but in 1968 and 1969, all the Hemi's had them. Any one have any definitive insight?
