Larry & Daryl;
I really figured Larry just had one of those so-called "Senior Moments" & posted the size for 13/1 rather than 13. 00While you were then correct in pointing out this would be a Range, rather than an exact number, I highly suspected that you just failed to actually think about the actual diameter posted, & just assumed that Larry had posted it right.

I am even older than Larry so fully understand Both concepts. Did want to set the record straight though less someone become confused.
