Norwood you are correct... That is the correct dill cap.. I have an 1970 GM A body survivor with the original valve stems and those are the dill caps that are on the car.I also have a buddy that owns a tire shop in Elk grove ,ILL that's been doing tires since 1972 til present... He also told me those dill caps in your picture is correct even for my 1978 trans am,,,,
