Subject: Sliding window glass removal

After searching with no good answers, I have to request some help. I have
both of my sliders out of the van. I have new window guides and felt to
replace. Also, I'm gonna tint the glass. Now the window guides and the tint
can be done with the glass still in the frame. But no way to replace the
felt channels without removing the glass from the frame. The one side of the
frame with the fixed glass has the break in it. But I'm to scared to attempt
to pry that end apart and bend the frame or worse, never get it to seal up
again. The seal that the slider runs in seems impossible to remove with the
glass still in, so how is this done!?! I can only assume that someone has
had the fixed glass broken and replaced, so it has to be feasable. Right?
Anyone?
