Hello- I realize I am in the wrong forum but hoping someone can be of assistance with this information. I have recently purchased a 190E 2.5-16 EVO II with only 2,800 km. The car is in fantastic condition, certainly one of the very finest remaining examples. My problem is the dust cover boots and bump stops for the rear shock absorbers have deteriorated. The shocks seem to be operating fine. Does anyone know where I can purchase these? Or if not available something extremely similar that I can substitute? Or 2 correct replacement rear shocks? Thank you in advance!
