I know about the later style, I have three of them. I was surprised to find the top on #13 was a Kayline top. Guessing the total number of early soft tops to be in the 500 to 600 range. Not a huge number for a aftermarket. I wish I could date the time it was made. It's not that bad of space, Clearly not top from the sixties. I don't have the V spaced frame for the doors. Either need to make some or have them made. They fit in three holes. One in the front bow. The other two required drilling holes in the top of the windshield frame and tub in the B pillar area. Since the holes are alreay drilled just going to keep the top on this one
