If your truck’s exterior mirrors are cracked, fogged, or failing to heat, this ECCPP pair replaces both driver and passenger sides with parts keyed to correct GM reference numbers (GM1320247, GM1321247). They match the fit and function of the original assemblies for a straightforward swap that returns your vehicle to proper road-ready visibility without custom modification.
