I agree with Karthik, this is a tough ruling for many teams. Veterans who have donated these parts to other teams should do as he suggests and make sure the word gets out.
As others have suggested, one easy solution for teams that need a quick alternative to additional KoP sprockets is
IFI's 35A24 kit (scroll down to Drivetrain Sprocket Specifications) for $9.99.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
