1986 280i Federal models

[cfsah]

Can anyone help me with sourcing the following

left hand steering rack...probably European?

ball joints .. I understand there may be two sizes but where did they come from.

the moveable metal parts of the steering must be nearing their lifetime so I need to consider their replacement. Who made them..Ford, the lowest bidder


Also the rubber federal black rubber bumper is splitting and the metal mounting hardware is all rusting out


Thanks for your assistance

Jim
