Roy Nacewicz is making the best reproductions on the market. They were patterned after a very nice pair of originals I allowed him to use.
His number is: 734-654-9450 or website, www.fordbolts.com
I will trace the one's in my 40 coupe and mail the template to you if they are the same as the 39. I made them from the originals years ago. They fit just fine.
