1967 barracuda 383 4spd on CL

It seems like ABS or unlimited products also used to make those spoilers around the era of the Holley three barrel and the Thrush chambered canister "Woodpecker Muffler"... the burning question in my mind is how much coolant did that car puke out everywhere when the knee knocker A/C was running? Didn't these cars have borderline adequate cooling to start with?
