My father in law has just purchased one of these mustangs along with a 69 boss 429. Anyways the 67 is suppose to be only one of 9 built from ford like this. It has functioning rear brake ducts, factory roll cage and a special high output 390. It has 12.5 to 1 compression. The car was appraised back in 92 for 58000.00. This is a stock car and was made by the factory for Lemans Racing. I am trying to find more information for him on the internet and was wondering if anybody new where I could find it.
