Doh.........I forgot they were off my 1st Chally.........a 72 which has the headlight buckets in the header panel
One had nothing, and the other had a chincy backing.
As for what to do?
Have you got in contact with the company that made you fiberglass fenders, and see if they happen to make this piece and it is possibly sold separately?
Or possibly getting in touch with other fiberglass resto companies to see if they may offer it?
