Roger,
Sorry that I am arriving a bit late but here is some input from the 1965 Wills 6 hour race and the 3 hour Challenge race where the Fleetwood Motors Mustang first appeared driven by Ivan Segedin and Dennis Simmons. 2 weeks later on October 23rd my sister got married (50 years ago ) and Dennis was at her wedding. I spent most of the afternoon following Dennis around asking Mustang questions etc..I think he was glad to get away from me pestering him..it was like I was talking to God !
Anyway here is some programme input.
