Lugnutz you are on to something. Can someone confirm the years that might apply to my contraption? Post below suggest 67 to 72, but is it out of place on an earlier 6 cylinder? Also what is the purpose of the carb extension otherthan fitment over the valve cover? And without the carb extension (using traditional air cleaner) what do I lose or is the carb extension required, in all cases to get the air cleaner above the valve cover?
