FRONT SUSPENSION LOWER CONTROL ARMS/WISHBONE REPLACEMENT

The next job on my list for the Octy is the front suspension control arms.

I have noticed an annoying knocking when going over speed bumps and the like.

I looked at the last MOT and saw and advisory for the Nearside front rear bush suspension arm bush rubber deteriorated.

Searching around suggests its good practise to get the whole control arm completely if your doing the work yourself! As this is easier?

Would the below be any good or steer away from the cheaper parts?

Also, just buying the lower arm bush on its own is more cheaper but how hard is it to attach to the old arm?
