Urgh. This being a former race car, there is no trace of the OE interior either. His only hope is the dash and glove box have never been out of the car so there is hope it may be under there.
Thanks for the links, Adam. I'll pass them on. This is a "M" code 440 GTS that has been raced for most of its life. It even has the original number match 440 so the new owner wants to bring it back to stock.
