flyboy, what you're talking about is the bottom bracket *shell*. The bottom bracket itself is all the crap that sits inside there. These days it tends to be a single unit like this guy right here:
Back in the day it would be loose ball bearings, some cones, cups, and the BB spindle. On American-style bottom brackets (any 1-piece crankset) the BB spindle and crank arms are one-in-the-same.
fixie.ninja, let us know what it ends up being. I'd be curious to know.
