Gary, they were at Sebring for the fall vintage races last year and were part of the Shelby colection out of Boulder(I think it was Boulder). With any luck they will be here next weekend. They said that when they came back this fall that they would bring a J-car. Anyhow, they were driven like they made them everyday. As far as these two cars go, I don't know much about the Mk.I. The Mk.II is chassis no. 1015. It was driven by Ken Miles and Lloyd Ruby at the '66 24 Hours of Daytona, giving Ford it's first 24 hour win.
The folks that brought the 40s also brought a 427 SC and a 289 FIA car. It was heaven!
