1965 Griffith

Hi All - I'm running into a problem in our re-build of a 1965 TVR Griffith once raced by Mark Donohue. We're in the midst of getting the engine back together but find the clutch is a mix of Ford and GM parts. Anyone have information on what they actually used and where can I find a new one?

Also - we're going to want to replace the motor mounts.....again, any ideas as to what these are?

Thanks!
DL
