Actually they also fit the rare 250cid four door Biscayne! But for 68-71 I need the ones with the little vertical lines in the logo, pretty sure.
It's funny because it's one of those things that I'm NOT really passionate about but I don't want some nut "judging" my car in 2 seconds by its lack of T3 headlights!

I came across a single high/low beam bulb with the vertical lines in my garage, but it wasn't where it belonged so I figured there might be an issue with it. While it looks good, a continuity check proved the low beam to be open. Bummer.
It's available if someone wants it. LOL.
I think I kept it in the event someone wanted it to display a full set.
I've burnt out probably 4 or 5, including ones that lost a battle with a rock.
