Driver fender is a hot mess...

Option 1 Direct interchange would be any 1969 dart.

Option 2 You can use a 68 dart fender but need to weld up the round light hole, and graft in the rectangular reflector flange from your original 69 fender. You will also need to remove the spotwelds on your 69 headlight bucket support mount out of your 69 fender and transfer that to the 68 fender.

Option 3 A 67 dart fender would need the same mods as the 68 fender with one exception. You wont need to fill a light hole, just add graft in the 69 rectangular reflector hole, swap 69 fender light bucket housing to the 67.

Option 4 and prob best option if you cant find a good used 69 fender is to buy a new AMD steel full 69 dart front fender, and not complain about price
