Rear Cab Floor Pan Cross Rail – 1973–1987 Chevy GMC C/K & 1987–1991 R/V Squarebody Pickup
The Rear Cab Floor Pan Cross Rail is a critical structural restoration component for 1973–1987 Chevy and GMC C/K Squarebody pickup trucks, as well as 1987–1991 R/V series models. Now available as a standalone part, this cross rail restores the factory support located at the rear edge of the cab floor pan, directly adjacent to the cab corners on standard cab and crew cab trucks. Designed for classic truck restoration parts projects where structure and alignment matter, this component reestablishes the correct foundation at the back of the cab.
From the factory, the rear cab floor pan cross rail provides rigidity and load distribution at one of the most stress-prone areas of the cab. Over time, moisture intrusion, trapped debris, and corrosion commonly compromise this section—especially near the cab corners—leading to weakened floors, poor cab alignment, and compromised body integrity. Replacing the cross rail helps restore the original strength and geometry intended by GM for Squarebody trucks.
Manufactured as an OE-style replacement, this rear cross rail is formed to match original contours, dimensions, and mounting geometry. Its design allows it to integrate seamlessly with the rear floor pan and cab corner structures, supporting proper alignment across the cab shell. This accuracy is essential for restorers repairing rust damage or replacing rear cab floor sections while maintaining factory-correct body lines.
Offered as part of AMD’s premium Squarebody sheet metal lineup, this component reflects AMD’s commitment to precise reproduction and restoration-grade quality. Unlike pieced-together repairs or modified substitutes, this cross rail is purpose-built to address the specific structural needs of the rear cab floor area. Making it available on its own gives builders and body shops a focused solution when full floor pan replacement is not required.
Correct for a wide range of Squarebody Fleetside pickup trucks, including later R/V series models, this rear cab floor pan cross rail is an essential piece for long-term durability and correct cab structure. Whether used in rust repair, structural reinforcement, or comprehensive cab restoration, it provides the proper OE-style support at a critical junction of the cab floor.
