WIW Opinions on a 69 Dart GTS.

I figure this. Decide how many $$ it takes to make it a great #2 car and subtract that from a realistic retail fair market value. That gives you current retail value in todays clothes. . What this car is worth perfect, I have no idea!
I will say this, few cars came with their build sheet, usually missing 5 wrong ones. Export cars were generally ordered by servicemen back in the day. Does not mean the car was ever out of the US.
