I just bought a 1987 300TD and need to replace the nitrogen chambers. When I did this on my w123 wagon a few months back I was able to source some lemforder brand parts from a local guy. For the w124 I'm only finding Febi brand and 'Genuine Mercedes' branded accumulators.

Does anyone know if there is quality difference for the 'Genuine Mercedes' part in this case? I've heard somewhere that many of the Genuine parts built by lemforder. Or is it possible that the Febi and Genuine part are the same thing at this point and I would just be paying a markup for the brand?

thanks
