I'm working on making mine water tight too. Would love to see how it goes for you as you're working on yours. I found rubbers at these two sites:

Does anyone have one of these around a good lead on one? I need one that has the two black & two blue wires, then a long black wires out the back like the one pictured. Thanks!
