This will get confusing....
The "Willment Coupe" was CSX2131...
"...In 1964 The John Willment Team of Chertsey England purchased CSX2131 as a spare chassis. Willment realized the aerodynamic advantage of the Pete Brock designed Daytona coupe campaigned by Shelby American. He decided to construct his own version based on drawings supplied by Shelby American with the help of John Ohlsen from Shelby American and completed by Frank Gardener of the Willment team.
Upon completion it was entered in many European and South African races."
...none of which was LeMans.
I would have to check further, but I think....
The 1963 AC team car at LeMans was a roadster.
The 1964 AC team car was the A98 Coupe...not the Willment Coupe.
...and this car should not be confused with
CS2131...the famous 39PH
The Willment Coupe is part of the Shelby American Collection, in Colorado
