Technical ID these bumper parts

Does anyone know what these bumper parts fit? They look to be mid/late 50's to early 60's to me. I got them in a pile of early Corvette parts but they certainly aren't Vette.

 

Cool but you got me stumped. I wonder if they're part of greenhouse trim, going by their size?

 

'68-9 Corvette

 

Yep looks like 68 corvette
Redo32 got it

 

Thanks guys. I guess they are Corvette after all....just not '56-'62 like the rest of the parts I bought.

 

Explains the shallow angle ... sharply pointed front end threw me
