anyone know how many 1971 Twisters were produced?

I owned a 72 340 4 speed twister. I bought the car in december of 73 from the salavage as the insurance deamed it a total loss. It was very repairable with only sheet metal damage and no frame damage. (it had been a roll over) Drove it for 6 years, great car. It only had 3000 miles on it when I bought it and it came with the sharktooth grill and both the 340 & twister call outs on the 1/4's. I have never seen another. I wish I still owned it as I was told it was a very rare car. I was told there were a few made but were usually ordered with those options.
