These were machined up for my SLK32 by a member on the MB C32 forum some time back but I never got around to installing them. Assuming the Crossfire chassis is the same (which I believe it is), these should work on any Crossfire as well. Solid 6061 aluminum rods and stainless rod ends. These are quite nice. IIRC I paid $250 for them. PRICE DROP $100 shipped in continental US!
