Query: Product needs a detailed description before I buy it.

The sleeve is listed with ID (interior diameter) numbers. I need OD (outside diameter) measurements (Duh..the sleeves fits on the outside, not the inside). ID numbers do absolutely no good. The Spectre products might be good, but I will never know if I can't get decent descriptions of their products. What a way NOT to run a company. A complete description, plus how to install, how not to install and potential installation pitfalls should be included on all Spectre products.
