Thanks for the reply. I have noticed that as well but never knew when the changes took place. If I ever show the car, I wonder if either jack would be accepted for my June built 1964 1/2? I'm trying to see which one I should keep in the car. The other one that came with my 64 1/2 (although these can easily be changed out by the PO) is described as you said, with the rounded edge handle.
