The Carb will be the easy item to find. You see them on Ebay from time to time. For 1967, you will want the carb where the fuel line comes in tangentially. The linkage is another matter. I remember a post on the OHC forum a few months ago where someone fabricated one until such time he could find an original. The problem finding the linkage is that many 1 bbl OHCs were switched over to a 4 bbl manifold, but the linkages were either tossed or never carried over.
