THe shims that I orderd from the dealer 4 weeks ago are still not here, One guy says they were back orderd, they'll be in tomorrow. Another says theyre backorderd he has no clue when they'll be in, manager says he'll look around the local dealerships for some, bla bla bla Just basicly constantly getting blown off. Poor customer service. So I think I found some crane valve shims, just want to make sure they are going to work before I waste more money on these damn things.
