Unfortunately it may not be that easy being that it's a Stanley. Stanley is no longer making entry doors. Unless I have been misinformed, the entry door division was aquired by Masonite about 8 years ago I believe. I too am looking for a replacement window frame for a customer. The door and window frame were painted hunter green and face the sun for the better part of the day. The frame is severly melted and falling apart. And yes, hopefully you haven't found the hard way that the frame does hold the glass in place and could easily fall out if disassembled.
