Temporary Speedo until I can get mine fixed

So the Speedo packed up again and trashed another angle drive. I took the speedo out and tried operating it with a speedo cable and drill and although it does function it's noisy and vibrates so it's definitely in need of attention and I'm going to need to send it away to get it reconditioned. As my car is due on the club triumph stand at the NEC classic show early next month I'll wait until after that. In the meantime I'll use a GPS Speedo to keep the car road legal.
