Body work/metal work magician needed

The fender is toast.. I don't understand why you want to get the whole car redone???? The only issue I see is the stripe. A good quality body/resto shop should be able to replace and repaint your NOS fender and blend the paint keeping your car 75-80% oem paint. The only problem I see is matching the color of the 40 yr old stripe...taking in weathering,UV damage etc...
There is no way to get the stripe to match and the paint will not really match either even if the color is perfect. There is no way to make new paint look 40 years old. The new fender will definitely look newer. I have looked into trying to get all the stripes off but saving the paint, doing just the fender, and every possible other course of action. I would rather not get the whole car done because as far as anyone I have talked to over the last 27 years has been able to determine it is the only one of the 53 '69 383 S 4-speed notchbacks made that is left with it's original paint but so far there is no one who thinks it can be made to look right without doing the whole car. That is part of the reason I have not done anything yet. I want to be DAMN SURE there is no way of saving it.
