I spent ages looking for one and failed. I used the web and severakl other forums.
In the end through this forum I obtained drawings and made it up my self.
It is not that difficult. The drawings should be treated as general arrangement and it requires a bit of double checking to make sure it will match and fit your machine body.
I still have them as PDF’s and can forward them if you give me your e mail by PM ( my messages)
