I need to purchase a new subframe for my 1986 560SL. I know at one time the 107 subframes were updated for strength. Does anyone know when this occured. I prefer to get one that came updated from the factory rather than strengthend acording to the service campagian. So far I have located two subframes one from an 85 380SL and one from an 84 280SL Euro.
