Looks like a repro to me. ‘68 came with a dull finish. The repops have a dull paint applied over typical chrome.
I replaced mine with the repops from from Classic Ind. They are an absolute BIOTCH to install. I also thought they wouldn’t fit, but with great effort and patience, they did. I scratched them up pretty good, so polished the rest of the dull coating off.
I'm a hobbyist. Not a professional. Don't be hatin'!
