Awesome mate, i need to replace the ones on teh GUIV too.

FYI in relation to the ride height change. Did you tighten the bolts up when it was still jacked up? If you did then you might have got increased ride height but now the bush is twisted and flexed. I would be undoing the bolts while it is sitting in the drive way and retighten them all while the car is sitting in its level ride position.

If you dont do it as above you will find you will flog out the bushes much sooner than necessary.

Cheers MR
