Any idea which Bilstein inserts these are?

I have a 77 with Bilstein struts. The insert on the left in the photo came out of the car and has no markings. The one on the right came out a sack of suspension parts that were sitting in my prior garage for 25+ years. In fact I have 4 of the ones on the right with a number of 0045001H002. My Google search of the number revealed nothing. The one that came out of the car is softer than the other four.

Any ideas? I'm guessing the four might be "sport" inserts?

Thanks.

Elephant Racing might know since they rebuild/modify these

What color are the bodies?

...and are there any engravings on them?
