This past weekend I replaced both strut mounts on my '91 300D. Although some articles in the Wiki were helpful, I did not see this procedure posted so I wrote it up:

The pictures are uncompressed and around 150kb each - I will try to reduce them later when I have some free time, but at the moment I'm getting sleepy.
Hope this helps someone out.
