This box is designed for select <strong>1978\u20131988 Chevrolet and GMC heavy-duty C30\/K30 and 1-ton dually applications<\/strong> and is described as <strong>really clean and rust-free<\/strong> for its age.<\/p>\n<p>The <strong>tailgate is not included<\/strong>, allowing this to be a straightforward option for customers who already have a usable gate or plan to source a replacement separately. There are some <strong>minor age-related flaws throughout<\/strong>, which are to be expected from a vintage truck bed, but the overall condition is notably clean.<\/p>\n<h3>Product Details<\/h3>\n<ul>\n<li><strong>Fits:<\/strong> Select 1978\u20131988 Chevrolet pickups<\/li>\n<li><strong>Fits:<\/strong> Select 1978\u20131988 GMC pickups<\/li>\n<li><strong>Applications:<\/strong> C30 \/ K30 and select 1-ton dually configurations<\/li>\n<li><strong>Bed length:<\/strong> <strong>8 feet<\/strong><\/li>\n<li><strong>Configuration:<\/strong> Dually \/ DRW<\/li>\n<li><strong>Style:<\/strong> Square Body<\/li>\n<li><strong>Condition:<\/strong> <strong>Rust-free and very clean<\/strong><\/li>\n<li><strong>Tailgate:<\/strong> <strong>Not included<\/strong><\/li>\n<li><strong>Cosmetic condition:<\/strong> Minor age-related flaws throughout<\/li>\n<li><strong>Price:<\/strong> <strong>$2,500<\/strong><\/li>\n<li><strong>Location:<\/strong> Wichita, KS<\/li>\n<li><strong>Nationwide shipping available<\/strong><\/li>\n<\/ul>\n<h3>Rare Square Body Dually Replacement Bed<\/h3>\n<p>Clean <strong>Square Body Chevy and GMC dually beds<\/strong> have become increasingly difficult to find, particularly rust-free examples suitable for restoration. This 8-foot box is an excellent candidate for a <strong>classic truck restoration, original-style build, custom square-body project, work-truck recreation, or replacement of a damaged original bed<\/strong>.<\/p>\n<p>The wide dually configuration gives the truck the distinctive rear fender profile associated with classic <strong>C30 and K30 1-ton pickups<\/strong>. Finding the correct DRW box is especially important because standard single-rear-wheel beds are not interchangeable with the dually configuration without significant modification.<\/p>\n<h3>Classic Chevrolet &amp; GMC Applications<\/h3>\n<p>This bed is relevant to owners of classic <strong>1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, and 1988 Chevrolet and GMC pickups<\/strong>, subject to exact factory configuration and fitment.<\/p>\n<p>It may be of interest for builds involving <strong>Chevy C30, Chevy K30, GMC C3500, GMC K3500, square body 1-ton, 454 big-block gas trucks, and classic diesel dually projects<\/strong>. Exact compatibility should always be confirmed because body and chassis configurations varied across these model years.<\/p>\n<h3>Rust-Free Condition<\/h3>\n<p>The <strong>rust-free condition<\/strong> is one of the strongest features of this vintage box. Older Square Body beds are frequently affected by corrosion around the <strong>wheel openings, lower bedside sections, bed floor, seams, mounting areas, and underside<\/strong>, so finding a clean replacement can significantly simplify a restoration.<\/p>\n<p>There are <strong>minor cosmetic imperfections throughout<\/strong>, but these are reasonable to expect from a truck bed that is several decades old. For a restoration project, the box provides a strong starting point without the extensive rust repair often associated with vintage Square Body body panels.<\/p>\n<p><strong>Price: $2,500. Tailgate not included.<\/strong><\/p>\n<p><strong>Please verify your exact year, Chevrolet\/GMC model, C30\/K30 configuration, wheelbase, dually\/DRW setup, bed mounts, and dimensions before purchasing.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>1978\u20131988 Chevrolet &amp; GMC C30\/K30 8-Foot Dually Bed \u2013 Clean Rust-Free DRW Replacement Box Rare opportunity to find a rust-free<\/p>\n","protected":false},"featured_media":37931,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[53,58,55],"product_cat":[30,45,40],"product_tag":[],"class_list":["post-37930","product","type-product","status-publish","has-post-thumbnail","product_brand-chevrolet","product_brand-general-motors","product_brand-gmc","product_cat-chevrolet","product_cat-dually-bed","product_cat-gmc","first","instock","sale","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 -
