The first grille bar looks like '54 Pontiac to me. Not sure I've ever seen a convertible top bow with a dome light built into it before. That bootwell trim might be worth a fortune if you can identify it.
X2 on the '54 Pontiac center grille bar........ That last pic is either a windshield or rear glass trim.........either GM or Ford, I think, not the correct shape for Mopar, in my opinion. Ray
