Here's my parents' '73 Formula 400. It's all original with the only thing missing being one of the ram air boots. It has been sitting for 15 yrs. and I just got it running w/ the help of a friend. It is going to be a long-term restoration. I have other priorities to pay for first. Things I have changed: oil, plugs, wires, cap, rotor, air filter, points(that got it running again).
