I am wondering how your restoration went/is going. I too have a '73 Gran Prix that I have recently started riding again. I replaced the tires and tubes and the brake pads. Everything else was pretty much a clean and lube effort. Now I am thinking about going a little further, maybe a paint job but don't know if that is something you can get done or not. I am clear this is not going to be a money making deal, more the nostalgia aspect as I am the original owner of the bike. Any thoughts?
