I have a pair of Bilstein inserts for Boge struts available - They are about 1.5 yrs old and are sport models (P36-0113). but I would say less than 5,000 miles on them. Top dust covers are not included, but you can use your existing ones.
They are in great shape - I only took them off to use some raised spindle bilsteins with custom inserts for track use.

Looking for $150 shipped for the pair
