All of them are kind of a PITA to mess with but I like the Dietrich the best. FoMoCo used these as accessories on some cars of the era. Dietrich made adjustable ones to fit more than one width. One of those would likely be better for fit on a pickup. Some folks like the look of the Fulton types but I'm not a fan of them. A person has to make sure they find one with all the pieces no matter what brand you choose. The center and outer clamp parts can be hard to find.
