okay, i'm a little confused here. the arms are attached to the aluminum part of the window frame via little plastic clips. these clips have cotter pins to keep the nubbins on the arms in the clips. as long as these are out, you can pretty much yank them out. it does take quite a bit of pressure. you can lever something underneath the regulator arm to pop it out of the clip. if you're talking about removing the two aluminum pieces on the bottom of the window, i wouldn't reccomend it. afaik, they don't come off. |
