I just bought a set of belts from Pelican parts for my 300D, after one of the alternator belts snapped and took out the other one and the PS belt.


I noticed that despite chosing the belts listed as OEM Mercedes, that they aren't ribbed. Does anyone know if these are still ok to use? My experience has been that you're supposed to replace like for like, but I don't know if these are still usable. Pelican Parts says they fit, but IDK.
