W124 shocks does a 2 mean HD?

[moruzzi]

I believe I need to replace my rear shocks (92 400e). Rear end jiggles cornering over rough pavement. Jacked car up and none of the links are loose after tugging on everything. THe existing shocks are black in color (so I'm assuming they are Bilsteins, and the plastic cover/shroud that is supposed to stay on the top is broken and sits down on the bottom giving a good view of the rubber bumper that should be replaced to) the only identifying mark is a large 2 on the side of the shock. Does anyone know if this identifies it as HD or Comfort? The car has 140K and I dont have any records of shock changes from previous owners, front sway bar bushings were changed.

Planning on HD's at this point since I'm not sure if I want to change springs in the future (I know I will get 16" wheels in a few months).

Thanks
