Rear wish bones? Trailing arms for an SE narrow

[Hairy toes eagle]

Hello, in the process of restoring an SE over the winter and need some new or better rear wish bones or trailing arms if that's the correct term, it's a live axle not independent suspension.

 

Great if someone could get in touch
