You mean disconnect the boot and ring from the console itself or the actual ring at the base that the boot is attached to?
This is all assuming the A/S attaches the same as the manual - it should anyway.
The ring itself has a lip on the front edge, so pull up from the back and it should just pop right up.
If you turn the boot upside-down you'll see it attaches with a series of small plastic teeth/clips around the edge of the bottom, the boot has slots that the teeth/clips go through and that's all that holds it in place. The boot is kind of rolled over the edge. You'll see what I mean once ya get it off.
That's sweet you found 'em that cheap - you can check
