Install Rating (3rd Party Work 10 = Best, 1 = Worse)
Air-rite Air Suspension model number W21-760-3004
should fit all Mercedes through 1980's 207d's, mines a 1985 and I was told this kit was for younger vans, but no it will fit 1985 and maybe earlier.
Installation was easy, I did it myself with the following tools.
Spanner and socket set.
Two axle stands
Drill and 6mm bit
A brick ( to put the bottle jack on)
A long screw driver ( to pry off the rubber bump stops, easy by the way)
A sheet of cardboard to lie on the road
Everything else comes in the kit
