Had the unfortunately experience of someone backing into the front end of my '68. Along w/ metalwork, the grilles we're bent/cracked. I'm trying to understand what pieces I actually need to replace. Sadly, they're beyond bending back into shape. It looks like there's 3 different pieces (not including the headlight assemblies which appear to be OK). My understanding is there is the grille itself, the outer trim, and the housing, is that correct?
