I knew of exactly one company that made them for 3rd generation rams but the name of the company has escaped me and I can't find their website, which isn't surprising because when I originally found them I looked for reviews on them and everything I could find said that they aren't a real reliable company and don't have a very fast turn around time when you order. It sounded to me like they built their sliders in batches, they would wait until they had a certain number of orders before they started manufacturing anything. I'm guessing they may have gone out of business.
