anyone know how many 1971 Twisters were produced?

Trying to fix this photo so it could be seen better
Hey simopar, I'm sorry I didn't see the image of a fendertag you posted earlier, like almost 3 years, haha. Gotta love FABO, never gives you prompts.
Anyway, it certainly shows the 'A51' Twister code and is stamped 'E55' and has an 'H' in the 6th spot in the VIN along with the VS29 meaning Duster 340 - hmmm. I also see a 'U' which is a US spec car.
With that said, do you own this car? Do you know of this car or did you happen on this fender tag? It certainly is interesting - so please give us more info. Thanks.
