1968 shelby gt350

[V8Dave]

Hello
I have friend that is looking to purchase a 1968 shelby gt350. I forwarded him the 68 shelby registrars name and email address however I was wondering if anyone might have a contact number for the 68 shelby registrar  Vincent Liska.
Thank you all for any help you may be able to provide.
Many thanks
Have a nice day
Dave
