need an assist
 

i have a 1991 300e 103.983 and would like to know if someone could help me in determining the correct torque for the bolts holding the rocker arm holding bracket? i see two values on mt cd manual 05-2190 has both 21 nm and 15 nm but the 21 is in the pictorial and the 15 is in the instruction.
thanks in advance

The same numbers (15 or 21nm) are given in the CD repair manual.
If I had to do it, I'd go in between, i.e. 18nm.
No one will see or feel the difference.
