Bilstein shock identification help

[dascoupeguy]

I need to idnetify what style/type Bilstein shock is on my 3.0CS. I am about 2/3's finished with my resto job and need to know what shock was installed prior to my acquisition.
The rear part # is F4 B46 0813 H001... Sport, Street???

I do not know what part # is on the front, but I can only assume (possibly in error) that the previous owner installed a matched set front and rear.

Thanks for any help.

For some reason the part number is same for both but the Sport is recommended only with lowering springs by Bilstein. This is from a 1991 catalog.

I called Bilstein on this issue. I was told the height of the sport and HD were so similar that only one type is listed (the sport). I used the sport in my Bavaria with factory springs and had no issues. Cannot recall which perch I set them on. ....Fronts are a different story.
