Guys I'm the Owner of a 88 Square Body Crew Cab Dually......with plans to more my mirrors from the current (tripod camper style) to the vent window location... SO My Question to Ya'll is.... Does Anyone Know the Heavy Duty Mirrors Part Numbers..... Powered, Non-Powered, Heated, Non-Heated, Just Curious.. I called the Local Parts Store (Parts Recyclers Style Store, Not Auto-zone Kind) and got some dude that was Obviously Not a Car Guy... Sorry Dude ya gotta have the years of the Vehicles.... (I'm Tossing around the Idear of Dodge or Ford Super Duty Mirrors As Well...) what ever Fits and Looks Best... Customization is NOT an Issue I can do that)
