drop the sub frame, slide the clutch out, lose the skin off your knuckles, £60 for the clutch (GSF) and £100 for the poor sod who has got to fit it (its a days work)
at least i think this is how they do it, i had two garages offer to do it for a days labour, save £350 and buy some gunk and clean the engine while its still in there (everything you can see you can clean)
