Tried https://www.davidsilverspares.co.uk/ ? They are usually pretty good for classic Honda parts.

A new one will cost you north of £120 otherwise you'll just need to keep on the lookout for NOS on eBay and Amazon.

As Evil Hans mentioned, davidsilverspares is a great address to get what you need. However, if you want it cheaper you need some luck to find someone who is offering it on ebay. But from times to times there are some auctions.
