Did you try Paul at JustEngines?
I have had success with his UK based business in obtaining parts for a re-build on my long out of production
Irvine .20 diesel.

Send Paul an email, he usually replies with 24 hours.
You can deal with him with confidence, his service is 1st class in my experience.
Parts will be sent to the US, no problem there.
