I had a '69 FD Victor back in 1976. Had a 100k on the clock, a lot for back then, but motor was still strong. Solid body but like yours, rust holes in the top of the wings. Bench seats, floor change gears. Still got the special tool for adjusting the valves.
That's something which has improved over the years. People just took it for granted that a new car would be full of holes after five or six years. At least they don't rust away quite so quickly now.
