These specifications are from my factory "Technical Data Manual Issue 1966" page 90. The hollow bolts have lock plates, torque to 20 mkg then deform the lock plate to secure. The big 22 mm nut uses a lock nut or cotter pin (early versions). Torque spec for those are 10 mkp. The torque for the three small bolts on the triangular safety plate is not specified in my TDM. You can measure the diameter of the bolt shaft and use a standard metric torque table for a guide. With the early MB cars like the pontons and 190SLs, the trailing arm mounting was the same. They did have a 22mm nut with a cotter pin to secure the trailing arm to the chassis, but did not have the additional 3 bolt safety plate. Well, terminal rust, left un-treated, caused the mounting points to fail on these early MBs models. The trailing arms would then drop down to the pavement at speed. Not good! Mercedes added the three bolt safety plate on the pagodas and all other models which followed.
