Will a 75 dart inner fender fit a 69 dart

FM3 Dart said

The stamping for a 69 inner fender and a 75 inner fender look completely different.
The 69 is smooth and flat where the 75 has a very large shapely area for the charcoal cannister and a/c components that the later cars used. They are completely different in appearance.
Will it fit? yes. Will it look right? Not even close

It's an inner fender! There is absolutely nothing that a '69 inner fender does that the '75 inner fender doesn't do. They are functionally the same if you're mounting the later inner fender on an earlier car. The only difference is cosmetic.

Can you tell the difference between the two? Of course, cosmetically they are different if you know what each of them looks like. Does it matter on anything other than a 100 point resto show car? Nope. Not at all. No one will even see it if you don't open the hood. And most people probably wouldn't even notice it if they're just looking at the car. Yes, they're different. But unless you know exactly what each of them look like, you're not likely to notice. Heck, even if you DO know what the differences are there's a good chance you won't notice if you're just looking at the car and not picking it apart for some stupid show trophy.

Sounds to me like the OP has access to a '75 inner fender, otherwise, why ask? Put the '75 inner fender on it and get it back on the road where it belongs.
