"I might sound like I want a medal for this job but it was pretty claustrophobic and twinged my back etc"

Any of us that have done a quadrant share your pain - its a naff job. First time I did it (albeit on a mk4), I removed the drivers seat, but then had the raised bit that the seat bolts to in the floorpan f*cking up my back instead. Got better at them over time but hardly in my top 10 of fav jobs!
