A bloke I used to know had a 73 Fastback mustang (mack I??) with a mild 460 in it. Quite a nice car, same color as yours. He was selling it last I saw. It'd ran a best time of 12.2 after an engine failure. I've probably still got his business car as he works for Bridgestone tyres. A mate (xbwgn) and I caught up with him years ago when we were picking up tyres from the factory to deliver to tyre shops.
