Description

Firewall – 1947–1955 Chevy GMC Pickup & Suburban ('55 1st Series)

Restore the core of your classic truck project with the Firewall – 1947–1955 Chevy GMC Pickup & Suburban ('55 1st Series). Designed for the beloved Advanced Design (AD) 3100 and 3600 series trucks, this firewall fits all 1947–1955 1st Series Chevrolet and GMC pickups and Suburbans. Whether you’re tackling a frame-off rebuild or addressing major rust in the cab, this panel offers a structurally sound and restoration-ready solution.

This is an X-Parts firewall, part of AMD’s third-party offering for products not yet manufactured using our in-house tooling. While it does not match the premium OE-style fit and finish of AMD-branded sheet metal, it’s a viable solution trusted by the restoration community. Some panels may require additional bodywork during installation, but each has been vetted for workability and structural use across countless real-world restorations.

Additional Benefits

Whether you're bringing a barn-find AD truck back to life or cleaning up a custom build, this firewall is an essential component in rebuilding the cab’s strength and structural integrity. It’s a common rust-prone area and a frequent target for modifications, making replacement the cleanest option. AMD’s X-Parts line gives restorers access to components not yet available in AMD’s proprietary stampings—bridging the gap with field-proven alternatives.

Each X-Part is chosen based on installability, material quality, and historical success in the restoration market. While it may require additional fitting and prep, it offers a practical solution when premium AMD tooling is not yet available.
