C-19 Smokebox front Diameter?

[Gunslinger_Fur]

Hey all,

I have a quick question. I'm readying myself for a little kitbash project in Large Scale and I need to replace the smokebox front with a more detailed one. I was browsing the Bachmann Parts site and saw the C-19 smokebox front replacements.

How much to they measure in diameter? Real life measurements preferred, thank you.

I measure 2 5/8" on mine.
