Got the formula for the Nuka Cola after I sold the 30 quantums to the Sierra at Girdershade. Returned to factory took cola formula from safe and finally found the red racer factory. But the Sudden Death Gang didn't show up. Is it too late now that 'day's in the game' have passed and I completed the nuka-cola challenge quest? Will LeDoux's ever show up?

No, you've missed out on it, you have to avoid completing the quantum quest until after you retrieve the formula. AshRandom (Talk) 20:49, 22 January 2009 (UTC)
