If a someone asks a question here you get the question answered. If your not interested in the experience and knowledge here don't waste peoples time and then complain about the answers.
Also, some of the people here are privy to information/experiences with several of these brands of seals - this is a common problem area.
We have to learn to just chill out: we should just state our experience(s) and let it rest (put our egos away). This type of "variety of experiences" also occurs when people ask about Pertronix ignition, or tube/tubeless radial tires, or ZDDP additives during normal oil changes, or the need for hardened valve seats, or the . . .
If you want to learn more about comparison of product information on rear seals, join the oldGMCtrucks discussion board and look of the discussion on these seals (by pros and by careful multiple-experience restorers).
