If you own an OBS truck, then you know that the cab corners can become severely rusted over the years. More times than not they end up needing to be replaced entirely. Holley Classic Trucks has got exactly what you need with our replacement cab corners for the 1988-1998 GMT400 Series trucks. These cab corners are manufactured for a precise fit and are made from heavy gauge steel and EDP coated for strength and corrosion protection. They will provide the quality and fit that your project needs.
