So that thing is actually one piece that goes across the entire width of the window frame, just like the current rubber windshield gaskets, with cutouts for the defroster air to pass through. But this isn't rubber, it's plastic of some sort that has the cords on each edge that form the bulb seals at the grooves and a corded body for thickness. Both sides were compromised, and thinking they were smaller individual pieces, I tried burning out the remnant of the inner piece. But upon further inspection I determined this is suppose to be all one piece. And what's left is not removable, it's trapped in there because the windshield doesn't fold and is non removable unless it's cut off. In fact, it was never intended to be removed because it can't, by design and manufacturing. Not a good design due to lack of maintenance access to an area prone to rust (as evident by the plethora of rusted windshield frames and cowl leaks). As far as I know, this is the only specific model and year of land cruiser that has this fixed windshield, which means virtually no info available of previous rectifications. Pissant.
on edit - it's vintage car type fender welt
