87 420sel
 

i working on the 87 420 trying to replace the mirror on the right outside.

i got a set right and left for about 15 bucks but the right hand housing is cracked so i'm trying to use the mirror and the motor.

can anybody tell me how to disassemble the right side mirror housing. i'm holding the one i just got but even with the cd info i can't seem to get the darn thing apart. any help is appreciated.
