In Ronnie Spain's "GT40 - An Individual History and Race Record," I quote -
"...Finally it was sold to Dennis Murdoch in Thousand Oaks, California, who still owns the car which is currently mid-way through a complete restoration. In the early stages of the restoration, rock singer Rod Stewart visited the Murdoch household with a view to purchasing the car, but no sale resulted. 1067 is unique in being the only Mark I sold new with a Mark II tail, which still wears it all these years later."
From the garage views, it would appear that Murdoch's restoration got about as far as taking it apart - and no further.
