Actually, I can't find your car there. But there is yet another route to easily find the M-B part numbers.

Go to www.startekinfo.com. On the left side of the page, choose "MB Workshop Resources" and below that click on, "Service manual library CD/DVD." This opens a menu with a single item, a link to the "Star Service Library." Click this and you will get a list of all of them. Unfortunately, I cannot find a manual for the 126 there. Anyone know the story?
