WTB: Steering swivel joint for 528e - 1983

[Bimmerfied]

My u-joint / swivel joint for the steering assy. has a little play, and I'd like to replace. I can feel it in the wheel slightly, and actually see the play in the joint itself. It doesn't appear to be service-able. Anyone got a good used part their willing to sell off?

Of course, I'm looking for a swivel joint that doesn't have any play and isn't seezed up. Good condition only.

Thanks.
