Try e-parts if you are after powerflex they seem fairly cheap. As mentioned earlier in the thread I can't recommend super pro enough. Just fitted the rear beam bushes took a while to get the old ones out but because of the 2 piece design it meant that they were an absolute dodle to fit. No need for any kind of press.
Just done 160mile journey on them and found that they have made the car feel much more planted and changes direction much more positively than before.
