Yours looked really stuffed, they are broken. They are called the rear pitman arms or the dogbones. I did mine about 1 year ago.

I didn't get the lemforder one, I think the brand was meyle. The lemforder one s give you new hardware like bolts and washers also, they are a bit more expensive.

Shogun gave me this link a while ago,

it tells you what to do. Its about a 30min job per side. If you can't get to it with the car level on the ground, reverse it onto some car ramps (the rear wheels on the car ramps). They are a simple remove and bolt-on item.

You can see the old to new ones here;

The ruined tyres are the symptoms of these and other bushes dying and not the 'cause' of the problem. Many a board member has done this work themselves. I may give it a go. Now I just have to log into BMA...
