The Roadworks Peterbilt Ultracab and Flat Top Post Mount Darwin Top-Tie Visor with Cab Mounted Mirrors is a practical and durable accessory for your Peterbilt truck. Made of stainless steel, this top-tie visor mounts easily to the center windshield post and two rivet positions below the mirror brackets on each side. The side of the visor is cut out for factory mirror brackets, eliminating the need for their removal during installation. This kit is designed specifically for Peterbilt Ultracab and Flat Top models from 2005 and newer, but please note that it does not fit cabs with 1 piece curved windshields. Mounting hardware is not included, and when replacing the factory fiberglass visor, existing holes will not be reused.
