I've just checked and the assembly procedure for the W126 3 part bushing is also detailed in the W123 FSM chapter 33-520!

The flats on the bushing need to be parallel with the flat part of the outer part of the control arm. This outer flat bit is the flat bit on to which you screw down the saucer for the spring.

There's a picture and everything => para 7
