If you need new sink strainer basket for disposal side of sink, you have to buy new disposal.
Each garbage disposal comes with its own strainer basket so that disposal can connect and seal.
First, the disposal strainer basket is installed, and then disposal lifts up and attaches from below.
A rubber gasket comes with new disposal.
Rubber gasket fits between disposal and strainer basket so that disposal seals correctly.
Photo below shows how disposal connects to strainer basket using steel connector ring under the sink.
I wrote tips for installing a disposal from days when I worked apartment maintenance.
