I like the retrofit JK sliders too and would also be hesitant to slice up my half door tops. Unfortunately, there just are not enough JK half door owners out there to justify large scale production of sliders. Bestop would have a set on the market if there was enough demand.Your what? You ordered the retrofit package? If so did you finish it yet? I really want sliders but don't know if I am brave enough to slice up my current half door tops to do this conversion. I wish someone just sold them, they make everything for jeeps, how can no one be making these sliders anymore?
