Will these cab parts fit my specific Peterbilt 379 model year?

The Peterbilt 379 was produced over a long span of years with some design changes along the way, so fitment can vary.

What materials and finishes are available for cab components?

Depending on the part, options may include steel, aluminum, or fiberglass construction, with finishes ranging from raw or primed surfaces to chrome-plated or painted finishes.

Some smaller trim and accessory pieces can be installed with basic tools and hand skills, while structural cab components like mounts or panels often require more extensive fabrication, welding, or alignment work.

Aftermarket parts are generally built to match OEM fit and function at a more accessible price point, but quality can vary by manufacturer.
