Now that i got a number, i need the 1960s period correct gasser/drag racing letters to go with the number, like A/G, A/GAS, or C/G. I'm thinking C/G or C/GG would be about correct. I know the first letter is weight to cubic inches and G was for gas and gasser class. They changed pretty often through the years. I want her to look like a retired gasser from the 60s that got her 283 replaced with her factory 6.
