The front end and rear suspesion is the same as the w114 and w115 cars. E.g. a 1969 220D. The big tires and heavy weight of the v-8 107 models is just too much stress on the control arm mounts. The 107 subframe used to even have a 115 part number. The major change is that the 107 had vented rotors. The 560 might be different however, as they had a redesigned rear suspension. Replacing the subframe is a big $$$ job due to the labor involved.
