steve/mbenz sent me some close up pictures showing a tape measure at several angles.
from all the pictures i looked at, they varied a couple of inches up or down.
i made a reversable template out of cardboard.
these are also available in orange [earlier models].
this style was used on w126,w107,w124,w202.
these plugged into the turn signal indicator wiring.
