I looked on Hostilesmoker and didn't see the guide, do you mean the one on
http://www.ftodiy.co.uk?
I've done both front and back arb bushes, back ones couldn't be easier but the front ones are a bit of work. The guide on ftodiy is good enough, it can be a bit tricky to get at the bolts on the clamps that hold the bushes in place, and it can be tricky to get the clamps back on but all in all its very doable.
