The crankcase pully (harmonic damper) on my 2002 SLK32 recently needed to be replaced so I ordered one from RockAuto.com. The part came from the UK but when it was to be installed it was noticed that the pulley had only 6 grooves instead of the 8 grooves like mine. When RockAuto said they would not pay the return shipping ($98.70) to the UK since it was not their fault because the part was for the European version of the car. I question whether AMG installed different pulleys, belts, etc on the version sent to America. Now, my need for help. Could somone in Europe check their SLK32 and see if it really has a 6 groove pulley. A friend of mine has a SLK320 and his car has the 6 groove pulley as I suspect RockAuto assumed that both cars have the same pulley. Thanks ahead of time for any help.
