OK,,,I guess I should have said Grease was depitcing the 50's.
Like I said "I could be wrong" (about American Graffity) Though I think you should as I will watch it again.
Either way, the 50's came before the 60's. LOL

I asked my dad how far back he used flame throwers and he said he had them on his 50 something Chevy in 1960.
He used a model T coil.
