I bought my '88 YJ about 3 weeks ago, and it has a Bestop on it which is in bad shape, so I took most of it off. I left just the very top, like a bikini top. It has the half doors with top half with sliders in the frames. The soft part of the top door panel isn't any good, but the actual sliders are still ok. If anyone is interested in them, I'll send a couple of pictures. I know that new top half doors with the sliders from Besttop are over $400, but I don't have a clue as to what just the sliders and slider channels are worth, but interested in offers.
