Flywheel Diameter

[pbgsho]

At some point Ford increased the flywheel diameter. Was this for 91 and up and what was the diameter?

Thanks,

The flywheel stayed the same.
The clutch disc and pressure plate went from 9 1/4" to 9 3/4".
Some small clutches have stayed in service for all these years, and cars are still being taken apart with the small clutches. But the problem was recognized and Ford authorized rework changes were being done in 1990 and the production cars were coming out with 9 3/4" clutches from the factory.

Thanks for the clarification. Have not looked at my SHOs for some time so I could not remember what had changed.
