All ,1971 and 72 Buick GS /GSX cars and Lemans /GTO factory ordered with UB5 hood tach should have tach vent assembly.
It was also installed in late 1970 as well. I own an Oshawa built 1970 GTO Judge factory hood tach car, 06B, 2nd week of June 1970 car and it has the hood tach heater nipple on top side of heater box.
