Rusty, glad you made it home safely! I was so lucky to reach the Retro Rides (RR) venue having lost three of four coupling screws approximately 10 to 15 miles from Cheltenham which was the time I started to hear strange noises from the rear. I felt a bit guilty drving the car mostly at 70mph+ despite my best efforts keeping the speed down to 60mph. Anyway, I took everyone's advice not to risk driving back to London in its condition and rang my breakdown cover. The rescue lorry arrived at 3:20pm, just amazingly, 20 minutes late. Left RR before 4pm. Arrived home at about 7:30pm. I know all have a quite a distance to drive, so hope everyone got home safely as well.
It was great to see everyone there. It was great to meet Ralph (and his son?). Many, many thanks for everyone's knowledge and support particularly Bis13 and Rusty. Ladislav, it was good to see you and many thanks for bringing all my stuff. Steve, you have an amazing car. I was hoping that you would drive the car around the circuit. Darrel, you were right about the coupling. We did not get a chance to do a deal on your treasure trove of Bis parts - perhaps next time. Pete, I took your advice and moved the car to the RR entrance. The rescue vehicle actually drove passed as its sat nav instructed him to do so. He made a u-turn when he noticed my car, so he could have arrived sooner.
I need to buy a new drive coupling and perhaps risk driving it the nearest garage.
