Tim john---'s 1967 GTO
(In His own Words)

I have owned my car for better than 32 years now, it is very much stock visually & externally (SD enhanced 670 cylinder heads). It is a factory H.O. four speed car. Factory original options include H.O., Power steering, Power disc brakes, Power antenna, AM/FM, Reverb, Rear window de-fogger, Rally Gages, Hood tachometer, Sport Wood steering wheel, Floor console, Deluxe Seat belts, Front & Rear floor mats, Soft Ray tinted Glass throughout, Safety Trac, Ride & Handling Package, Red wheel well liners & original HURST wheels. I also run an orignal 66 Tri Power w/ Factory steel Ram Air pan.
