I'm not sure why everyone is pushing the 3101 adapter kit. Everything you need comes with the Waste King L-1001. I ripped out the old 3 bolt mounting system and installed the new EZ Mount that came with the L-1001. It's installed, it lined up exactly as the old In-Sink-Erator 3 (Badger 1 Model) disposal, and works fine without having to buy anything extra.
