Mark, I called Peter @ Carserve and left a voice message. He called back, but in the meantime Nick has ordered a compressor + clutch from the US.
Peter Wayte at Car Serve (http://car-serve.co.uk/contactus.aspx) said he can normally get hold of 260 compressors from his UK stock at short notice (sourced from Germany).
He also seems a very helpful guy and is willing to take a call from anyone requiring help in sourcing or fitting the compressor.
Many thanks for the recommendation, I would certainly have used Peter had we not already ordered one from the US.
All the best, TC
