I know what you mean. My car was pretty much original when I got it, but you just don't know what was changed over the years. Stuff was worked on. Move one thing to get to another. Maybe put something on wrong...I continue to try to get details right. A little more convincing when something the same on several cars especially if they are 'survivors' or look relatively untouched. Yet I am sure people could look at my car and not realize that EVERYTHING was apart and put back together. I don't know if I got it right. If you get down to the nuts and bolts, I guarantee it is not 100%. I would bet people look at yours and copy details. They could copy something that you have not corrected yet or don't even know about.
