Don't think many places will stock something that old these days. I have a blue and silver 2.8 and needed some blue paint to tidy up under bonnet and in the boot. Went to a local car paint supplier and and he still had sample charts going back to the 70s. We matched it with calypso blue I think and also cross checked using Google . He then made me a large rattle can up for about 10 or 12 quid and it's not a bad match at all.
