HELP-I'm in the middle of rocker removal & I'm stuck

[passthebuck]

Hey all. My appologies to whomever I borowed this pic from BUT its a good view. Its not my truck but it is the same area. I'm in the process of changing out my passenger side rocker-BUT I'm having trouble-at the rear i drilled out the spotwelds easy-its loose there and at the front i've remoced the two bolts in circles #2 & i've drilled the spotwelds at #1 BUT it wont pull loose-what else is holding it in place? Is what is holding it in place inside circle #3 OR is it on the backside? Do i need the fender off to un-do what is holding me back? I'm flying blind here & i'm open to all suggestions-Thanx!
