Upper Rear Toe Links

[Rhino]

While trying to find the cause of my intermittent suspension knock I've found some very slight play in the upper rear toe arms, these look to be original Mazda items, so time to be replaced.

What's the normal replacement for these, from looking at the parts manual the hub bushing is actually a pillow ball? Is it better to replace with Mazda parts or are the rose jointed toe links any good?

Thanks
