Kelly,

On second though, I believe = you’re right and I was wrong. Creavy works with ID, not CL. =

Cary,

Thanks for the input.......What we are trying to do is = get final and absolute

numbers on the sizes required........One of the first = requirements is for all to

be on the same page with measurements.......Previous reports = have shown

ID's , OD's , Center diameter and/or total length........I seem to remember reading

a previous post that "Creavey" preferred working with = a ID measurement

but Mark just posted that the Center diameter is what they use = ?? Bottom

line we all need to be on the same page among ourselves and with "Creavey".

FWIW
