Cuda on the bay misrepresented
The only things he is correct about on the 66 vin. are the 5th digit D did denote the engine size & the last 6 digits are sequential production numbers. The D was on both 2 & 4 barrel cars. If it is a true 66 formula s the fender tag would have a 32 under the AB for the 4 barrel engine & a 7 under F for formula s. The 65 fender tag would have a 31 under AB for the 4 barrel engine & a 2 under C for formula s. Shame he seems to be Bull S*%#ing. Decent looking car except for mismatched wheels.
