Hi again
Don't have time for sourcing today but these are some of the sources I used
www.1stchoice.co.uk will distribute details of your wanted engine to lots of different dismantlers, etc.., I had a lot of replies, lots of variation in prices, conditions, warranties, some will deliver
www.volvocarparts.co.uk also got back to me very quickly
