Terry, in my experience most top bows have a radius of 7-8" on the corners, regardless of make of car. Only very large cars were of greater radius. My motor trimmer filled me in on this detail when I made the jig for laminating bows. The radius in the jig is fixed at 7", and the jig is adjustable for width. I did once have to match a bow at 7.5" radius, and did so by packing out the corners with a couple of laminated fillers, before starting on that one bow.

Hope this helps.

Thank you
I couldn’t find anything about the radius. I had some made and looks a little bigger than what I’m taking off. But there only 108 year's old. The new ones are 6 1/2 inside 7 1/2 outside.
