E body hood pin diffrences

[antonellomopar]

Hello
can somebody please educate me on hood pins differences? I have bought several repro set in the past, and have some old used ones. But I am not sure on which is which, I mean, can't recognize what is original and what is OEM. The pic in the picture is OEM or repro? Thank you

Do they measure the same? I could send you measurements of the one's on my 1970 car which should be original.
