Looking for p/n help, with a general Q
 

Search didnt help me much... so here it goes,

im wondering how the side mirrors come apart, and what parts are replacable on a 02 C230 Kompressor

Is the clear lens for the turn signal replacable, if so does anyone have the MB part number?

if not, how much of the mirror housing am i going to have to replace? and what is the p/n
