New OE turn signal switches for '62-'63 & '64-'66
The lane-change feature started in '70, IIRC, and is called…
(wait for it)
…the lane-change feature!
I think this switch will work in the later cars, too. I'm just not willing to say so til I have concrete "tried it!" proof to go on. If it'll work in a '67 it'll also work in a '68 and a '69 (all three with same OE part number). Should have news soon!
And yer welcome; thanks for the thanks.
