It’s on the fender tag and it’s real for sure. Known this guy since college days and he finally came to the conclusion that his health and financial situation would not let him finish the car. I bought it yesterday. He had owned it since 77. Tag had been in place and never been touched. Loaded out cuda. He removed the original 3.55 sure grip in the late 70 and installed a 4.10. He sold the 3.55.
