New OE turn signal switches for '62-'63 & '64-'66

Now I've got a mystery on my hands: Will these switches also fit and work in '67s, possibly '68s, maybe '69s, too? I think they "probably might", but I don't have a '67-'69 car or column to check. I sent one to a guy with a '67, and one to a guy with a '68, and will report here what they find. In the meantime…they're known to work in '62-'63 and '64-'66s!
