There is one for sale on eBay but they want £150. I have a friend that repaired one for me, and he might do another one if required. This does require the old one sending to him. I probably will see him at a classic car show this Sunday, so I will ask him if it is ok to pass his details to you. The one he did for me looked stronger than the original design. I think he would be looking at about £30 + postage.
