here is where it got dicey. since its the bottom pane it is a real problem to remove. so pieces is the best way, problem its not all broken into pieces....
So i had to hit it with a hammer to cause the unbroken section to break into removable pieces. I was really scared I may shatter a side panel or cause a stress crack when I hit the bottom.
got lucky.
first pic is the just after the hammer,
second pic is as far as I got today, unfortunatly I have to eat and get ready for work.
