WTB: 67-69 Dart Fender

The car is a 68 as in my sig. I was under the impression that the only difference was in the marker light which I can work around.

So can I use other years or will I have issues?

Alot of people have that impression partly because fiberglass fenders are sold as one for all three years ( using your own headlight buckets )
Side markers are the other issue. Do you need both fenders or just one side?
