Replacement wheels for my screen sllider

Hi, This is what the wheel assembly looks like, I broke the wire part off removing it. This does have a metal wheel, not plastic other than that it looks like an 84-101. What do you think? Also I watched the video to take the wheel out but I'm not understanding what to do with the Phillips screwdriver to wiggle the wheel out of the little holding bracket. Any suggestions? Thanks, Liz

I would like to order replacement wheel assembly for my slider,84-101 looks like the correct part but I would like a metal wheel. Is the part number different from the plastic wheel?
