DL's online functionality sucks in this situation. Drop your hopes and call. Be prepared to tell the agent exactly the flights you want. The change will be free. However, if you MUST be at your destination at a certain time, as you said in your OP, I suggest going as early as possible, maybe even the day before. You may need to play phone roulette to get an agent to give you the day before for free, if you can get that at all.
