110 bcd is really common, you will have no problem (unless you want 1/8" in which case you will need to spend 5 extra minutes on google)
op: You're spending money for no reason. Return the bb or just stash it for a future project, keep the existing cranks, and simply buff off the rust if it's just on the surface and the part is not actually falling apart.
