Flywheel identification

[R72Demon]

I have 3- 130 tooth flywheels for 10.5 clutch I am trying to identify. All 3 are part # 2264598, but all 3 are drilled differently. Thanks for any help!

Same flywheels. They are simply drilled to balance each one. Since the metal density cannot be exact on each flywheel, there will be some differences in the balance.

Are they all neutral balance? I figured they were drilled differently for different applications?

I appears? that two of them have the same casting no.?

The external balance wheels I've seen have large recesses, resemble a hole saw, maybe? 1 1/2" dia or so. Of course they were made with a mill

All 3 are the same casting #

Here are pictures and explanation of balancing holes. No Guessing

Yes. They are simply drilled a little differently to each achieve neutral balance because of different metal density between each one.

My educated guess is that they are all 3 neutral. I would have a shop spin them to know for sure. It's a lot of work to put a car together, and find out otherwise.
