1st let me say that OE AMG/Bilstein shocks actually are quite rugged - and other rear components and quality of rubber should be checked 1st before shock replacement. Often OE shocks will go out past 200K with minor useage/seepage unless you have genuinely blown them out.
Do am forum search - Bilstein work fine - but you need to find the correct/new Bilstein #'s.
Replacement front or rear is very straightforward - search/find the pictorial shock replacement post on the standard W210 forum - I think it may be in their stickies - but research the correct Bilstein part#'s from a search here on this AMG forum.
Keep the faith !
