Windshield removal W126

[MS Fowler]

According to the FSM, there are supposed to be some heating wires embedded in the adhesive that retains the W/S to the body. I can't see them. I am looking on the outside of the left hand pillar after removing the trim. I do not know if this is a replacement W/S or factory. If it is a replacement--do they have the heating wires, or is that factory only.

Is piano wire. or hot knife the next best way to remove the W/S? I don't care if I break it. I am removing to make sure there is no rust before I repaint. The W/S is so full of sand pits that I will not reinstall it. The dash pad cover is poorly glued, and I want to see if I can remove and reinstall that, too-- so removing the W/S makes that job easier, too.
Any other removal tips/ advice appreciated.
