Now I'm really confused...or else I'm being particularly dense today,
I took the two wishbones off a wrecked 20v, they carry the above numbers,
are cast(forged?) of some sort of steel (they have some rust and a magnet
sticks to them)and accept a 3 bolt fixing ball joint. The wishbones on my MB
are pressed steel and take a 2 bolt fitting ball joint.
What gives?
