94 rear speaker replacement

I cant figure out how to remove the rear side panels in my 94 ext cab silverado to replace the speakers. Any help, advise, or links?

I did mine last spring (93 ext-cab) and had to remove the entire side-rear panel. It was a PITA, and be sure to remove the cubby holes on the panel before trying to remove the big piece. I learned the hard way, and cracked it a little. If I remember correctly, I also had to remove the fold down seat and back panel before I could get to all of the screws. Good Luck!

thanks for the help i hadnt thought about removing the panel behind the rear seat and i obviously need to remove more screws, that must be where they are. THANKS!
