Does anyone know what the inside diameter of a reverse drum bushing would be reamed to when new.

I need the measurement after the bushing is installed and reamed.

I'm not at home to look it up in my books. So far I have had no luck online.

I have found what I think is a NOS reverse drum. If the busing in it measures as a NOS measurement, it will help confirm my idea of the drum being NOS .

Thanks

Vic Zannis rebuild book states original dimension of the Reverse Drum bushing as 2.302"

Thanks Dan. My bushing is 2.303. It is the same at both ends. That's close enough to make me think it's NOS. Two different people can easily be .001 difference due to technique or equipment differences.
