Audi a3 Sportback 2.0 Tdi rear wishbone bushes? newbie

Hi

I require some rear wishbone bushes. the ones that help adjust the rear camber - i am not too sure how else to describe them. i was told they are real old and need replacing. cant seem to find the part as audi do the whole arm which has the bush in it.

I think that poweflex do some of these bushes. Are these any good and can someone pls send me a link? or can i get them from europarts?

Any help would be appreciated as i am very lost with this. (I think its no 8 in the picture)

Thanks

Do gsf do the original audi ones or the powerflex ones?

Bunp anyone?
