1968 vs 1969-72 Headlight bezel.

What is the difference between the '68 and the '69-'72 headlight bezel?

Thanks.

As far as I know they are the same. I think I read something about 68's having a headlight washer option but I've never seen any with it. If so, it is possible that those models would be slightly different. I do have a set of 68 bezels kicking around and I'm pretty sure they are the same as 69-72.
