I appreciate your passion for wanting to know about markings ....Man you picked a difficult one as far as overall correctness and location..I worked those assembly lines for many a year and there are soooo many variables here...The colors and markings and proper locations would vary for a hundred different reasons..Different inspectors, relief people, 1st to 2nd shift, vendor part changes, early to late model cars..This list is endless...I wish there were set rules here but thats just not the case...Survivor cars are excellent resources obviously....Good luck with your search..This is a tuff one...
