Front wishbone rear bushes?

[PUL54R]

Hi, anyone know where I can get a pair of replacement rear bushes for my front wishbones? I am aware that powerflex do lots of bushes for the pulsar, but they dont list rear bushes, only front ones. If I have to get new wishbones then any idea on the best place/price?
Cheers in advance.

buy a whitline castor antilift kit, that is the bushes you require

These? - For an extra 10p you can have the caster ones.
