Not sure of the best place to stick this - so mods feel free to move. My E36 current has an M50B20 single mass flywheel (I'm told with correct pressure plate and clutch plate fitted) and being honest I hate it, maybe I'm just getting old. Anyway - I'll be replacing with the correct dual mass unit in the not too distant future.

Would be happy enough to swap with someone who wants to get replace their own dual mass version.
Is there much demand for the single mass item?
