68 dart fender interchange

69s aren't the same.
The headlight area where the bezal sits is deeper, so the screws won't even come close to lining up.
'70-72 won't work for the reason that they have the removeable fender cap.

I know that the '73-'76 Dart fenders will fit and retain the headlight bezals, if you use the '68 plastic bezal screw inserts and the marker light hole s easy enough to fill and relocate.

I do have a '68 driver's fender here that needs a minor patch at the lower edge and the bracing is not rusty.
A simple patch would fix it.

Mark.
