All of these parts are on a mid June 1968 Cougar GT-E that I am restoring. All GT-E's were built in Dearborn.
Working on the seat tracks today and came across something unusual. One seat track (nearest one in the photo) was painted a semi gloss black. It has a logo that appears to be an "M" with an "A" superimposed on it.
The other three have a unique rivet that has the letter "T" in the middle and the one nearest the camera (second one from front) also has a date code that appears to be 8 65. These all appear to have had a clear zinc coating originally, no sign of any black paint.
I am used to finding these painted semi gloss black, all of them in '68 that I can remember. Any ideas?
