Topside,
i welcome the input.

I've owned my A12 1969 road runner since 1981, it was built in June of 1969 at Lynch Rd and the interior is original, it hasnt been recovered and all the buttons are the long type like we made (see attached pics, black seat)

the buttons we made measure 2.13" + the spacing on the posts 1.58" center to center
its hard to see in the pics but how tall are the buttons you have?
and the post spacing on those?

ALL the 1969 cars i found online have the buttons like my car has and what we made except i only found 1 69 similar to the buttons like you have

all of the 69 seats I've had in the past all had the long buttons like i made

maybe it was a plant or vendor variant??
