CARB number help

Hello all,
I need a little help.
I need to rebuild my carb to pass emissions, but the tag with the carb number is gone. The local parts shops can't do anything without the carb number. I know there are books that list carbs by application, but my manual doesn't.

I have a 67 cuda 273 2barrel, 3 on the tree, it's not an emissions car.
The only thing useful on the carb is it's a Carter, and also says Ball&Ball.

If you have the same engine/tranny set up, or a book that lists carbs by application, please let me know what the number is.

Thanks
