8 1/4 bearing adjuster

Actually I saw that over the Christmas holiday and the expected delivery
because of the holiday was about 10 days out. I didn't want to wait, but if I actually bought it then I would be probably be driving the car. Anyhow I was like a dog without a bone trying to find it somewhere other than Amazon mostly because of the time factor and the part it self was $15/18 with shipping being about $30 of the selling price, which for some reason is never a problem for me, but for some reason this time it was. It's really hard to believe that a fairly common part that should be available at Napa, Advance or AutoZone is currently unavailable pretty much everywhere and will be for sometime.
Common part? I have never seen one broken or needed.
