The Cab Back Molding Kit – Under Rear Window is an OE-style exterior trim restoration component designed for 1981–1991 GMC C/K and R/V pickup trucks. This three-piece molding set installs directly below the rear cab window and restores the factory-correct appearance specific to GMC Squarebody and early R/V series pickups. It is an essential detail for classic truck restoration parts projects focused on authenticity and correct exterior trim presentation.
From the factory, GMC pickups utilized unique rear cab molding that differed from Chevrolet counterparts, making accurate replacement especially important for correct GMC restorations. Over time, original moldings are often damaged, missing, or removed during repainting or rust repair. This exact-fit reproduction restores the proper visual break beneath the rear window, completing the rear cab design as originally intended by GM.
Manufactured as an OE-style reproduction, each piece in this kit is formed to match original factory dimensions, contours, and mounting locations. The three-piece configuration mirrors the original GMC layout, allowing the moldings to align correctly across the width of the cab. When installed, the set integrates cleanly with surrounding body lines and rear window trim, preserving a factory-style appearance.
This molding kit is correct for GMC C/K pickups from 1981–1986 and GMC R/V pickups from 1987–1991. It is designed specifically for pickup truck cabs and is not intended for Suburban or Blazer applications. For restorers seeking to maintain stock appearance and proper GMC-specific detailing, this cab back molding kit provides a correct and reliable solution.

Auto Metal Direct is a team of true car guys with years of experience in sheet metal reproduction, car restoration and paint/body work. We believe that quality is not subjective! Our mission is to provide the best customer experience for the Ford, Mopar and GM classic car markets - both in products and in service.
Our panels are made from proper gauge steel and include all correct-as-original clips, tabs, flanges, bends and seams. Each time a prototype body panel comes off of a new tooling, we test fit it on a car. The marked up prototype is then used to change and improve the tools, and a new prototype is produced. This procedure might be repeated multiple times but, once the part is finally approved, you can be assured of a quality part.
