JD 35G Side Window Replacement

I have a JD 35G with a broken slider window. The glass is about 3/8" taller than the frame but will fit in the track once it is inside the frame. It looks like I have to take the frame out of the cab in order to replace the glass. I see no fasteners of any kind on the frame. It almost looks like it is glued in place. Does anyone have any idea on how to replace the glass or remove the frame?
