IB, you are correct in that this would be great for a lakester or rear engine roadster and were very expensive new. I bought the car and spares from Doug when they switched over to Lola’s and when I sold the car, some of the spares didn’t go with it. This was a spare that Doug and later I had for the car and I believe its new and has never been used. Tony
