I agree those FIAT door panels are neat, and I have not seen em either. But I don't get to see a lot of Fiats.
Car looks like a project. That can be good, gives you something to do to stay out of trouble. Or it can be bad, if you like getting into trouble
I debated how to deal with my 72, and decided to just make it a rolling restoration. Which means it rolls a lot and restores a little. Little by little it gets nicer, and I get to drive it too. First things I did with mine was just make it functional, everything works, it runs well, it is a joy to drive. I pick up odd parts here and there, and little by little fix dents and rust. I really hate doing anything major that takes it off the road even for a few days.
That dent in the LR is very fixable from my back-yard bodywork point of view, although you will have to pull the fill tube ( a hassle) to get in there and work on it.
That broken lense bezel, everybody has one of those they would give you cheap.
Back seat, who need a back seat??
