How do you remove bucket seats from 2000 Astro van?

On my 2001 Astro there are 4 bolts from the seat frame to the floor remove the bolts

and the seat is removable (HINT move the middle passenger seat back as far as it can

go and that is easier to remove the seat and frame ..I have done this twice on the 2001

and 3 times on the 1989 I had..
