69 dart front end on a 73?

what exactly is the difference in the fenders?

I tried 67 fenders on my 69 the front surface where the headlight brackets attach was further forward.

I then tried fiberglass 73-77 fenders (told they were for a 69 when I bought them at a swap meet) headlight buckets width were to short to bolt to the rad support along with some bolt holes not lining up and grill mounts were off.
