Access is good and all other things being equal it would be a quick easy job.
However, all other things aren't equal - the bush was well stuck to the bolt that comes through the anti roll bar leaving two options: a) Blowlamp and let thermal expansion do its work or b) Hacksaw the bolt off and replace it.
It was a bit close to the petrol tank for carefree blowlamp work but as it happened grit, determination and the blowlamp did do the job.
I'll post some images in case anyone else needs to try this job.
