71 demon production numbers

Man y'all are quick! Thanks! I picked up one today with that combo. The 3 speed is gone, but the guy is gonna look for it for me. Highly unlikely he'll find it. It's a project car, and just trying to find out "how rare" to decide if I should go back original or make some changes. e.g. Disc brakes, 5 speed, ect. Any opinions? Pics in the resto section are soon to come!
