As Hurricane John alluded to, Joe died in Jan. 1964 in an accident at the Riverside 500 in CA. That season started in Nov.'63 & he was leading the points at the time. He was a former two time NASCAR points champ. If I recall correctly, Joe did not like the restricted feeling of 5 way seat belts & only used a lap belt. I believe he died of chest & or head injuries.. I think he was driving a Ford, but I'm not sure & I don't have info about his age.
