67 - 69 A Body Convertible Top Switch Repair
Well I was so close....
I forgot I have the top switch that came out of Dart #2, that I disassembled to clean.
It was still a part and I found it in my parts hoard.
I was spot on in the length, diameter, hole depth for the spring and the ball top was super close.
Turns out it's more the shape of a crayon.
