Frequently Asked Questions About Peterbilt 359 Windshield, Wiper & Roof Accessories

Will these windshields and accessories fit my specific year Peterbilt 359?

Most windshield and roof accessories for the Peterbilt 359 are designed to fit models from 1967 through 1987, as the cab design remained largely consistent throughout production. However, minor variations exist between early models (1967-1979) and later models (1980-1987), particularly in windshield gasket profiles and wiper motor mounting. Always verify the specific year range listed for each product, and when in doubt, contact us with your truck's OEM or year for confirmation.

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

OEM windshields typically feature the original DOT markings, proper tint gradient, and exact curvature specifications of factory glass. Aftermarket options often provide excellent clarity and fit at a lower price point, though some may have slightly different tint shades or thickness variations. For show trucks or restorations, OEM glass maintains authenticity. For daily drivers, quality aftermarket windshields offer great value and performance. Both options should meet DOT safety standards.

Can I install these windshield and wiper components myself, or do I need professional help?

Windshield replacement requires proper tools, technique, and usually two people to avoid stress cracks or improper sealing. Professional installation is strongly recommended for windshields to ensure proper fit and prevent leaks. Wiper arms, blades, and motors can typically be installed by experienced DIYers with basic tools. Roof accessories like sun visors and cab lights are generally DIY-friendly, requiring only basic hand tools and careful attention to mounting instructions and seal placement.

How do I know which wiper arm length and blade size I need for my 359?

Standard Peterbilt 359 trucks use 18-inch wiper blades with matching arms. Measure from the wiper pivot point to the furthest point the blade needs to reach on your windshield. The wiper pattern should clear the driver's primary viewing area without overextending past the windshield edge. Most 359s use a parallel wiper system, but some custom applications may have modified setups.

What roof accessories are available, and will they require drilling or modifications?

Common roof accessories include cab lights, sun visors, air horns, and antenna mounts. Most aftermarket cab lights require drilling five evenly-spaced holes across the roof front. Sun visors typically mount using existing mirror bracket holes or require minimal drilling. Air horn brackets often utilize existing mounting points when possible. Always use proper sealants and rubber gaskets to prevent water intrusion. Template guides are usually included with accessories requiring precise hole placement.
