I can't speak to what you have on your truck, but the specified part numbers for the control arm, shock, and bolt are the same for the model years based on the EPC site. The bolt part number is N308676014002.

I also came across this thread, where someone else had a broken bolt and had to drill it out and re-tap the threads:
1998 ML320 Shocks or Struts ? - Mercedes-Benz Forum

Also note it's possible the Sachs is different than the Bilstein shown in the video. it could be there's a separate busing on the bottom vs the integral one on the Bilstein.
