I was racing at Fremont drag strip the weekend that movie was being filmed, I had a white 1963 Plymouth Belvedere two door sedan 415 HP A/SA. I also owned and race a original 1963 425 HP two door hardtop Belvedere as a pro class bracket car
I and Don Wann both raced a lot at the national and division 7 races back then, we became friends and he would help me when he could and visa versus
He was very lucky to have Dave Rettig as a major sponsor
I saw him several years later win a race at Fremont with Dave 1965 SS/CA 1965 Dodge when it broke a ladder bar going into 3rd gear and he still won that round and fix it in the pits and went onto win that SS race
Don was a really god driver, his Son Stevie learned well also
