Hey guys, I finally got myself to replace the cam and the rocker arms on my 450sl. However, I am having a hard time finding Mercedes OEM rocker arms for it. The dealer wants $82 a piece for the arms, but Febi made ones online are selling for $20 a piece (I will need 8 of them). Is it worth buying the Febi ones? I also decided to change out my Timing Chain Tensioner, and ran into the same issue. The Febi one is $130, compared to the dealer at 552. Anyone have any issues with Febi parts in general? Is it worth the extra 900 dollars to go with the Mercedes parts?
