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
