How many CURRENT owners of real '74 360 Duster 4 speed cars on here?
Did the 360 emblem have pins on it? If not, and just a sticker, perhaps it was removed?
What day of the week was your car produced (off of fender tag or the VIN sticker on the door)? Perhaps it was built on a Friday and never got the holes drilled for the 360 emblem?
