Frequently Asked Questions About Mack R Truck Windshield Accessories

What year models of Mack R trucks do these windshield accessories fit?

Our Mack R windshield accessories are designed to fit R-Model trucks from 1966 through 2004. This includes all variations such as the R600, R685, R686, R688, RD600, RD688, and RD690. However, we recommend double-checking your specific model year as some late-production models may have slight variations. If you're unsure, contact us with your VIN and we'll verify compatibility.

Are these windshield accessories made from stainless steel or chrome-plated steel?

Most of our Mack R windshield accessories come in both options. Our stainless steel pieces are typically 304-grade stainless with a mirror polish finish that resists rust and corrosion without requiring constant maintenance. Chrome-plated options feature triple-chrome plating over steel for a brilliant shine but may require more frequent polishing to maintain their appearance. Product descriptions specify which material each item uses.

Do I need to remove my windshield to install these accessories?

No, most windshield trim and accessories can be installed without removing the windshield. Items like windshield trim strips, corner pieces, and visor brackets typically mount over existing glass edges or bolt to the cab structure. However, if you're replacing the complete windshield gasket or installing a full surround kit, professional installation is recommended as improper handling can crack the glass.

Will aftermarket windshield visors interfere with my CB antenna or air horn placement?

Standard drop visors extend 5-7 inches from the cab and shouldn't interfere with most antenna or horn setups. However, if you have roof-mounted accessories positioned close to the windshield area, measure the clearance before ordering. Our product pages include detailed dimensions, and many visors feature notched designs specifically to accommodate common antenna placements on R-Models.

How do I match the finish of new windshield accessories to my existing chrome?

For the best match, identify whether your current accessories are polished stainless or chrome-plated. Stainless has a slightly darker, more subdued shine, while chrome appears brighter and more reflective. If your existing pieces show rust spots or pitting, they're likely chrome. When mixing old and new pieces, a professional polish job on all components can help achieve a uniform appearance across your entire setup.
