I'm not sure what's wrong with Autozone's gaskets but I've tried 3 on an F-150 power steering pump and all 3 were broken during the tightening process out of round and didn't seal. At the end of my ropes I decided to order them. I figured I had a lot of chances of getting it lined up right. Although I didn't really need that much. I could tell right away from the packaging that they were sturdier and of better quality. The first walked and held his form through the first lap. THESE THINGS ARE AMAZING!
