Diff mounting - spacer tube (DON'T DO THIS)

The diff has to have a spacer tube fitted. (Why only one rather than in both mounting holes I don't know!)

It has to be fitted in a similar way to the bushes with constant force. The vice/G clamps weren't large enough so foolishly I tried knocking it in. DON'T DO THIS!!! When they say use constant force they are saying it for a reason. The end of the tube started to splay out as it was going in.

To save further embarrassment I didn't take a picture.
