A Couple of 65 Cuda Questions.

I have 3 chrome pieces that go below the rear window on my 65, two of them have the round Valiant V on them and one has the Barracuda on it. Is this a year to year thing or could it be a difference from a Canadian produced car over a US built one? My other question is, I have two trunk lids. One has holes in it for the Plymouth letters, and one does not. Again. is this a year thing, or a Canada/USA thing? I'd just like to know what would be correct for my car. I'm not doing a correct restoration on this car, it's just going to be a hot rodded driver but I'm really curious about the differences.

Regards
