2000 Astro Armrest removal

Does anyone know how to remove the armrests from newer (2000 on etc) Chevy Astro/GMC Safari seats?

I also have a 1990 and that's an easy deal. I have had those on and off several times. On my 2000 however, not so obvious it seems. I have tried the same push and turn method used on the 1990 but with no success. Haynes manual shows nothing.

Thanks
