Torn gasket behind speedometer gear box

[jimbonaut]

Well there is, but it's torn and in a right old state. I had a look on CMSNL but they aren't available - is it something I can make out of regular gasket material? What exactly does it do anyway - stop the grease from the speedo gearbox flying out?

yes you should be able to make one if you have a similar thickness material. I am not 100 % on it's purpose, might be a dissimilar metal insulator???
