Chevrolet Camaro 1967-2002 - Interchangable parts?

Wasn't sure exactly where to put this so please excuse me if this is in the wrong section. I'm pretty sure these parts are interchangable but I just want reassurance and in case they aren't, I won't waste my time on them. Can a '67 grille, with the circular turn lenses, fit in a '68 and can a '69 lower valence, also with the turn lenses, fit on a '68 too? Thanks for any help.

the 67 grill should be interchangeable. as far as the 69 valence, i would assume so. it may not just bolt right up you may have to modify it slightly but i don't know how much

Thanks, hopefully someone else will chime in and give some input also.
