Wiper linkage broken or 'popped off'

Yeah thats what I mean about the spindles. You can see on that one where the chrome has worn through.

It might be possible to turn them down and fit a repair sleeve with new bushings. A grease fitting on the housing would help too.

This is the cover I made. The original is the same shape but has a larger hole in the centre so is really just cosmetic. This one will hopefully keep the spindle relatively well sealed from the rain.
