My dealer tells me he couldn't use the EZ Slider tool to remove my sliders on my '04 500ss. The claim is that the track windows are to small. It the standard 1" track. In the past you take tghe screw out of the front and work it back witha pair of vise grips. They said they had to take the suspension out!! The only reason I didn't do it was lack of time with work and sub-zero temps in the garage.
