W126 self leveling rear shock/struts

[gear-head]

I have a pair of rear self leveling hydorpnumatic shock/struts removed from a (Jan production date) 1986 560sel. I was told by the owner of the car that they were working fine before he started parting the car out. There were no signs of leaks, the rubber dust boots aren't very good condition but they are still there for the most part. Will take $40 each plus shipping.
