The BESTfit Black Powder?Coated Aluminum Inner Door Panel for Peterbilt 359 & 379 and its passenger-side counterpart are sturdy, paint-ready interior door panels designed as direct replacements for classic Peterbilt 359 (1967-1987) and 379 (1987-2007) trucks. Crafted from durable aluminum and finished with a black powder coat, these inner door panels come with pre-drilled mounting holes for easier installation and are sold individually, select either the driver or passenger side. The passenger version includes a window cutout where needed, while the driver side is available without one, letting you choose the right panel for your cab restoration or repair. Because these are aftermarket parts (not OEM), confirming your truck's year and side application before ordering helps ensure proper fit and compatibility. Each panel is backed by a warranty against defects in workmanship and material from the date of purchase, offering confidence in both function and finish as you maintain or refresh the interior of your Peterbilt.
