Need help identifying odometer gear - 1986 911

[Farreem]

I'm in the process of replacing one of the odometer gears on my 86 911. I took everything apart tonight and sure enough one of my gears is completely disintegrated. I believe it is the 20x30 gear but not 100% sure.

Can someone confirm what gear is highlighted in red? This is the one I need. This is not my pic - I stole it from another post while trying to confirm the gear size.

Thanks!
