I am justing starting on a slow rebuild of a Dec 69, Metuchen build M code Mach 1.
As you can see it has had a very bad paint job - originally white.
I have been taking pics as I strip off some of the trim and noticed this detail - the car seems very original under the trim, I have the black detail around the alloy rocker moldings etc.
There front DS guard molding had a nice red oxide paint run where the top rear screw insert went into the panel. Also I did not find what left the mark in the paint but there is a square imprint in inverse which is quite noticeable.
Not sure if it will help anyone but I thought it interesting.
