the tops Lou has shown in his post
the right pic is the kellison top that vern was offering years ago but didn't pay the vendors so the templates and engineering was lost
the problem with copying it is it has front and rear molded fiberglass bows. the top would have to be destroyed beyond use to copy and my feelings are i don't want to even think about having a hartz cloth top remade. to guess, as i had looked into it previously, would be in the 3 to 4 thousand range to make
