They're too thin to be load spreaders.

The rings will help distribute the load a slight amount, but these rings are so thin, they will not offer any significant pressure more than a couple millimeters from the head of the bolt.

I have pondered the "3-ring" notion today. I suspect Ford trucks may not have had auto trannys before 1965, so when the Curisomatic was dropped into a light pickup, Ford engineering may have wondered whether a heavily abused truck might be able to cause the flexplate to creep and loosen under the short flywheel bolts.

Longer bolts have a shank stretch which would allow some flexplate creep while maintaining clamping force. Since manual flywheels FT trucks of 1964 had used these longer bolts, it was possibly thought that first-edition Auto-trannied FE pickup trucks of 1965 might do well to run these longer bolts until it was proven the shorter bolts wouldn't loosen up over time and abuse.

Just my latest thoughts on what that ring is doing there.

Shoe.
