Thanks! I figured with all the research you had done, that you had found those. I just wanted to make sure. I think any extra diameter with the clutch will help!
My other slant 6 cars run a 10" mazda / ford diaphgram pressure plate. It was not a direct bolt in however, they have custom flywheels... but they are heavy and steel, unlike this car that has the aluminum flyweel and the lighter pressure plate. All good things for road racing
