Looks like a couple of 11 inch flywheels there. I had to look around a lot to find mine and I've been really pleased with it. I'd pay to have one resurfaced professionally. Makes a big difference. Have them check the balance after they resurface it. Not normally an issue but nice to check it anyhow...especially if you need to shave off much metal.
