have you considered powerflex bushes ?
Meyle diff bush is very popular- I've used myself, but you can use powerflex too. Meyle seems very hard to get down there...Imcomex had them but you should email the manager at Centurion if you want any decent service

He's name is Gavin Holtshausen- very efficient guy there and will surely be of help. Attach foto of the bush on your email so it helps them match to their catalogue
The BMW one from agents is not too expensive and lasts a very long time so I'd go for that too. But the powerflex set for the rear suspension is said to last a lifetime
I've only used powerflex bushes on the lower control arms and ARB ..and have stiffened an old suspension admirably
For guibo, I've used Febi on two cars. I bought a febi guibo in the uk and one at Goldwagon also febi two years ago and both have been good so far for around R500 each
So I wouldn't necessarily go to agents and pay through my nose
