Trailing arm repair questions Options

[HalfMoon]

Lol, this may be a bit confusing.
My PO told me the driver side trailing arm bushing would likely need replacement and teh inner bushing/shaft certaining had movement when rocked up on a jack. The passenger side seemed fine but I decided to pull em both off and inspect/repair (at the very least rebush em).
Lot's of odd stuff upon dis-assembly and inspection.
Let's start with the passenger side. No movement was detected at the bushings when rocked on a jack. Upon dis-assembley (I lucked out, noting was too difficult other than the crown nut) I did notice that it appered a previous ear repair had occured and that there was/is some "slight" ovaling of the shaft hole. But remember, there's no movement and the bushings "look" fine.
Here's a picture

Also, a picture of the inboard end of the shaft (notice "slight" wear)
