I have a set of Bilstein PSS9s and after I got them installed, aligned, cornerbalanced I think the guy at the shop misplaced dampening adjusting piece. I assumed it was in the box with all the other spare parts, but to no avail couldn't find it. Where can I buy this piece?

 

When I got my pss9's the adjusters were on the shocks already. The rear shock adjusters were the only ones that were needed to be removed for installation. Are these the ones that are missing? they are located on the top of the shock body as oppose to the bottom as on the fronts.

If the shop you had bought them from can't get it, bilstein has a rep in North Carolina. see below.
