Been hanging on walls for years. It has the right angle tube for the BBC application. Has flame arestor with 4 small dimples and GM twice around base. The breather tube has 5 grooves. 2 grooves and small space then 3 grooves. GM at least 2 times along the length of grooves. I think base came off a 68 BBC camaro. Any ideas? Did the rubber valve cover hose change during the different years (67-69)
