Trailing arm rear assembly 390?

[dwgriffith]

I am about to start ebaying my hoard of wedge parts but one of the trailing arms has a larger diameter half shaft of 2 inch with bigger uj's. It looks like the wheel bearing, halfshaft and uj's have been recently replaced. The question is which model does it fit? (early 390?) or is it simply an upgraded version suitable for all models pre a frame.

Hi there I am after a half shaft with good U/J's for my 89 350i with A frames if you have one!

Cheers
