I had originally thought the leak, seen by water on the cabinet floor and on the disposal itself, was from the sink flange, a quick check and order of the replacement gaskets went great, and I received them within 2 days of the order placement.
It was not until I actually went to replace those that I discovered the support gasket for the disposal itself was all wrung out- the most likely cause of the leak, confirmed after putting to back together for the sink gasket replacements.
So another order for that part and in and other 2 days I got it - replaced it - and the issue has been resolved.
