I'm wating for the previous owner to post me the Haynes manual for the
car.  He says its a 4 spanner job, the only previous 4 spanner job I've
done before was changing an autobox out on a Vauxhall Carlton, which was
actually pretty simple, but my experience of taking french cars to bits
tells me that lots of things fall apart when you disturb them.  )c:  I
spoke to 1 mechanic who said he wouldn't touch my BX's clutch as he'd
had a bad experience in the past.

I've had a quick look under the BX and have seen some sort of
hydropneumatic looking device just under the radiator.

I have had 1 quote so far from a local Citroen specialist (old mill
motors in Aberdeen) for about £300 - your £170 sounds much better!  I
only paid £100 for the car, knowing that it would need a clutch, but not
knowing how much I would be charged for one.

Ah well, you live and learn.  It's a cracking car to drive other than
that, will need some stepper motor attention next I think. (c:
