You will not be able to drift the bolt out, so in light of that here is the definitive answer to the problem
Chop off the bolt, remove the upper arm, then belt the middle out of the bush with a mash hammer, it will not resist I promise
Of course you will have bought your new rose joint bush, if not.... phew you won't need to break the bank, as the identical part is fitted to E46 BMW rear suspension, so treat yourself.........

Now comes the interesting part, without further dismantling of the rear suspension, buy yourself one of these.......
LINK, I'm sure I don't need to elaborate on how this is used, or do I?
I've got a Vectra B rose joint tool, for which I machined up a deeper mandrel to accommodate the longer 75 bush, however I would have probably bought the tool in the link if it had been available at the time.
So, no need to start dismantling any further, if you wanted to be creative, after bopping the middle out of the bush, you could hacksaw through the outer part left in the trailing arm, then simply drift it out, remove the boot from the new bush, then after cleaning out the hole in the trailing arm, pull it into place using threaded bar, and a suitable size socket, or even the old bush housing with a big washer.
It's up to you, with the tool I use, the whole operation will take you less than ten minutes, I'm sure improvisation may take longer, but the end result is a whole lot cheaper and more satisfying than paying for an unnecessary part.
