You mean rockauto sent you two driver's side seals? One word of advice: If you buy parts from rockauto you MUST inspect them right away. Have had many issues with them. One of the latest was I bought 6 NGK coil on plugs and when I installed them 2 months later, the coils inside the NGK packaging were Bosch!! The only one that an NGK turned out to be dead on arrival! That one was sent to NGK who analyzed it and sent me a free replacement but I was stuck with the Bosch coils which is OK but you get the point. Also, bought a set of Sachs brand rear shocks for our van both of which crapped out after 2 years and less than 20,000 miles. I can go on, but this is enough. I will not buy from rockauto ever again. They are cheap for a reason
