Goodmark Valance Panel

Goodmark Valance Panels: OEM-Accurate Steel for Classic Car Restorers

When it comes to restoring the lower bodywork of a classic muscle car, few components are as visually impactful — or as prone to rust and road damage — as the valance panel. Goodmark has built its reputation squarely on delivering steel replacement panels that honor the original factory design, and their valance panel lineup is a strong example of that commitment in action.

Goodmark was founded with a clear mission: to give classic car rebuilders and restorers access to high-quality sheet metal without the futile hunt through scrapyards. Their valance panels — both front lower and rear lower variants — are manufactured from steel and engineered to match OEM dimensions as closely as possible, making them a go-to choice for enthusiasts tackling period-correct restorations.

Steel Construction with OEM-Referenced Fitment

Goodmark valance panels are produced in steel, echoing the material and construction method of the original factory parts. Each panel is referenced against OEM part numbers, ensuring restorers can cross-reference their factory documentation with confidence. For example, Goodmark's rear lower valance panel for the Dodge Challenger (GMK2120875701) references OEM part number P5153402 and is available specifically for dual-exhaust models — the kind of model-specific detail that separates a true restoration part from a generic patch. Similarly, their front lower valance for the 1968–69 Dodge Charger (GMK216102568) cross-references OEM fitment for those iconic B-body builds.

Coverage extends across several of the most beloved American muscle nameplates. Goodmark offers front and rear lower valance panels for the Ford Mustang (including 1964–1966 and 1967–1968 model years), the Dodge Challenger and Plymouth Barracuda (1970–1974), and the Pontiac Firebird (1970–1973), among others. Some variants are offered with exhaust cutouts or without, matching the spec of the vehicle's original exhaust configuration.

Electro Deposit Primer (EDP) for Rust Resistance

One of Goodmark's most practical advantages is the application of Electro Deposit Primer (EDP) to their sheet metal panels. This electrically applied coating works like a plating process, pushing rust-resistant primer into every contour and corner of the part — areas that would otherwise be difficult to coat by conventional spray methods. The EDP finish requires only light scuffing before paint, making it a ready-to-work surface straight out of the box and giving the restored panel a fighting chance against the corrosion that likely damaged the original in the first place.

CAD/CAM Engineering and Exact-Fit Design

Goodmark uses CAD/CAM (computer-aided design and computer-aided manufacturing) software alongside modern tooling to ensure that every valance panel is dimensioned to align cleanly with surrounding sheet metal. Each part design is test-fitted to verify proper appearance and alignment before it reaches the customer — a quality-check process that reflects the brand's roots as a company founded by and for car enthusiasts.

Whether you're pulling a barn-find Mustang back from the brink or executing a concours-level Challenger restoration, Goodmark's valance panels offer a steel, OEM-referenced foundation that serious restorers can build on.
