this is funny because when i got mine a month or two ago the parts guy took forever to find the right ones and comes back and says he feels dumb. they all have the same part # just diffrent amount's. mine takes three there's some that take 4? and other's take just two. i dont know how smart this guy was but mine fit. napa has some brute strength(i think is the name) that are supposed to super strong. another high end joint is strange or moser. good luck and any one feel free to correct me if i'm wrong.
