68 Barracuda grille surrounds
Here's my park lamps before and after.. I dont have a pic of finished grilles handy. Mine are hybrids, 67 grilles with 68 inserts.
I dont know where the stainless surrounds came from mine are aluminum too.
There are T bolts that will replace the broken studs very easily. I find it simpler to remove the entire header panel and lay it face down to access the grille mounting studs.
