Frequently Asked Questions About Peterbilt 359 Cab & Related

Will these cab parts fit my specific year Peterbilt 359?

Most of our Peterbilt 359 cab parts are designed to fit models from 1967 to 1987, which covers the entire production run. However, there were minor changes throughout the years. Parts for 1967-1985 models are typically interchangeable, while 1986-1987 models may have slight differences in mounting holes or dimensions. Always check the product description for specific year compatibility, or contact our team with your OEM for verification.

What's the difference between aftermarket and OEM cab parts, and which should I choose?

OEM parts guarantee exact factory specifications but come at a premium price. Our aftermarket options are manufactured to meet or exceed OEM standards, using similar gauge steel and finishes. The main differences are price (aftermarket costs 30-50% less) and availability (aftermarket parts are typically in stock). For structural components like cab corners or floor pans, both perform equally well when properly installed. For show trucks, some customers prefer OEM for absolute authenticity.

How difficult is it to install cab corners and floor pans? What tools do I need?

Installing cab corners and floor pans requires intermediate to advanced metalworking skills. You'll need a MIG welder, angle grinder, cutting tools, clamps, and proper safety equipment. The process involves cutting out damaged sections, fitting new panels, and welding them in place. Most installations take 4-8 hours per panel. We recommend professional installation if you're not experienced with bodywork, as improper installation can lead to rust issues or structural problems.

Are your cab parts available in different finishes, and how do I match my truck's paint?

Our cab parts come in three finish options: bare metal (ready for primer and paint), black primer, and chrome (for applicable parts like mirrors and trim). Bare metal is the most popular choice as it allows for proper surface preparation and paint matching. For paint matching, we recommend taking a color sample to your local automotive paint supplier. Note that original Peterbilt colors may have faded over the years, so matching to your current paint rather than the original color code often yields better results.

What gauge steel are your replacement panels made from, and will they hold up to daily use?

Our replacement cab panels are manufactured from 18-gauge steel for doors and side panels, and 16-gauge steel for floor pans and structural components, matching original Peterbilt specifications. This thickness provides the same durability as factory parts and is suitable for both restoration projects and working trucks. All panels feature proper stamping and reinforcement ribs where applicable. With proper installation and rust prevention treatment, these panels will last as long as the original parts.
