1. Here are the seals and such we ordered from NPD to make our assemblies factory fresh and leak-free. The vent window seals consist of two parts: the large V-shaped piece and the straight strip with the little tabs. The glass, which is offered in clear and green tints, is cut to the factory shape and has the proper curvature to fit in the framework. The roll of fuzzy stuff will run down a channel and provide the seal for the door glass itself.
