Missing Dash VIN

I purchased a 1972 340 Duster with a four speed a number of years ago and it has been my project ever since. I am in a dilema at the moment. It is missing the Vin tag on the dash. I have the vin number in the door jamb and the fender tag. The stamping on the rad support and the package tray are correct. I am not doubting that the car is a factory four speed 340, but i don't know what to do about the missing dash tag. It is really bothering me. I have looked into having one reproduced but have had no luck. If anyone has any suggestions as to what i should do i would greatly appreciate it. I just dont like the fact that anyone and everyone will be able to see that it is missing.
