I have been restoring a 1967 912. While it was at the body shop getting a fresh coat of paint, they lost the aluminum ID tag that goes on the front. I have been looking around, and found blank plates, but does someone know where to get these properly stamped? The 912 is stamped from the backside, and vin number stamped on front. I have all proper documents to prove it is "wow" real 912... Any help would be great!
