Unsure what best to call it but I am chasing the alloy piece that has both internal and external splines which the wiper plugs on. It fits on the top picture and looks like the bottom picture.
 
I don't know if they are available separate of a linkage but mine has decided to flog out and I need one.
 
Anyone able to spare one please?

They r all a bit cheesy - best to drill a hole right thru the spindle and splined bung and "pin" them?

What do people do? Drill cross ways and put a roll pin through?
 

They are most likely the same as mk1 escort so you should be able to find one in the Uk (ebay UK or escort specialists)
