It's been a while since I've measured one, but I believe .013 was the correct original thickness. I suspect .012 or .014 would work.

Thanks, Ron.

I could only measure the edge of the broken section, still attached to the arbor and wound tight in the case. It's a little rough looking, and, of course, not a flat surface, so my measurement is prone to being over.
