Let’s call them window sliders

at these prices you would think you could keep the snails off the plate
I agree whole heartedly, but for about a year I couldn't find ANY of these and therefore couldn't reassemble my car. I guess beggars can't be choosers. By the way, I think I ran into this before - my windows are really hard to roll up and down and it seems to be tightness at the sliders. Are yours the same? I think the only way to get them loosened up is to roll the window up and down about 50 times. I think that this was true 15 years ago the last time I did this.
