Parts Store Rant, the other side of the story

It doesn't help that the catalogs are getting worse, too. Raybestos used to have great listings with tons of info. Now they don't even tell you drum diameter, or cylinder bore sizes. Looking up some Monroe shocks the other day, two choices, and all the description told me was "71223 is a registered trademark of Tenneco Corp, and can not be used without permission". How exactly is that going to help me decide which shocks are for the station wagon?
