Well, my wife is 4’ 10” and when she commandeered my ‘69 GT back in the 80s for her daily driver, I had to make removable pedal blocks for her to drive it. After I did that, I only got to drive it once in a while!
I found with my 68 that the bench sits a little higher. When I switched from bench to bucket, I was sitting slightly lower and needed an additional pillow to sit on.
