For the W124 CD, the info is on disc 2, Chasis, Steering, 46-8110. I overlooked it the first search, but found it later. I really dislike not being able to use search functions, but when you do find the correct section, the info is very good.
BTW, I also have a 4" x 7" book that is kind of like a parts manual. I think the official name is "Catalog of Illustrations". I never hear people refer to it in these forums, but I find it a nice compliment to the CD. I think I will do a post and advise members to ask the Partsshop if they have them.
