This is a Totally Stainless 55-59 Stepside Shortbed Complete Bolt Kit. This Kit is specific to the 58-59 trucks, but will work on a 55-57 as well (theres a few bolt quantity differences with the front fenders and core support etc). There are a few bolts missing for the front bumper brackets and rear fender supports, but 90 percent of everything is there. This goes for $429 new, im asking $340, comes in original box, even a couple packs of antiseize in there for ya
