Matt, thanks for that - the last time I looked on the parts cat the repair kit wasn't shown - I just checked & it is now there on the manifold illustration.
Part number for the repair kit is 059 198 212 £8.15 + VAT
However.....the manifold runners we have changed have been shot inside - excessive play in the bushes (or none existent bushes), so possibly worth a disclaimer if you're going to fit the repair kit?
