Ok.. i've just recently purchased a 1972 Petty Blue Duster 340 with a blue interior, factory disc brakes... the car is rusty.. typical floor rot.. but because it's a factory petty blue 340 car with a blue interior.. it's worth fixen her up!! the only thing i'm worried about is if it's real... the dash in it has the vin, and i have a build sheet.. but where else can i find the vin on a duster?!?! The original motor and trans are gone.. i was told there was a total of 6 places.. but where?! and is there more?!
