If you're talking about whiskers that attach to the stainless pieces that attach to the glass, they are spot welded to the stainless channel itself.
This one

I started down that path of cutting them out of the channel, but soon realized, that's now how you do it. I cut the whiskers down the center, scraped it out, found the spot welds, cut them off, and the whisker strip came off from the channel. Then, I glued the new strips directly to the channel. total time took me less than an hour once I realized that they were just spot welded on there.
FYI - My glass guy struggled with the channels from Classic for hours on one window. He said that the window channel was super cheap stuff and just wasn't that flexible. He gave up and we went to Steele Rubber (an hour away from him) and bought some more flexible stuff and put all four windows in the truck in less than half a day. Granted it was more expensive, but it was worth it.
