Looking to replace my rear slider with a solid window. OEM gasket is discontinued. Rock Auto shows WBL3971 as the gasket, but doesn't specify for slider or solid window. Found this " CRL Truck Sliders fit into standard OEM factory back glass gaskets. Some pickups are equipped with a wide channel gasket (Fig. 1), on original equipment sliders. These are not acceptable for installation of CRL Truck Sliders, and must be replaced with a narrow channel gasket, such as those shown in Fig. 2. WBL3971 is for a CRL slider. Makes me think it will work for a solid rear glass. Can anyone confirm?
