I am hoping someone can help me with my ZF HP22 Gearbox. I will say that it is not fitted in a Sherpa, it was removed from a rotten riot van a few years ago (not by myself I might add).
The gearbox is being fitted to a 3.9 Disco engine and then into a Morris Marina coupe.
Anyway, could someone ID the top plastic connection on top of the tail housing? Is this a breather? How would it have been connected in the Van?

Second question: How dose the speedo cable work on the sherpa? Should there be a drive wheel inside the tail shaft? Can anyone help me find the right bits to make it work?

I really appreciate your help.
Regards,
Ben
