Not sure what you mesan by by loose, the gasket should be snug on the glass. If you have the gasket for the stainless trim, thee mouldings go in the gasket before installing in the truck. If the gasket isn't staying on the bottom arch, masking tape will hold it. Just did mine Sunday and remembered another tip. A suction cup is handy to help pull the Windshields into the A post. If the gasket doesn't fit the corners good, carefully work a piece of rope or screen spline into the groove. With a new gasket I like to give it a few days for everything to settle in before shimming. Sometimes the rubber just needs to form to the body. Also, if you chase the threads in the division bar, don't run the point of the tap into the moulding like some dummy I know! Hope this info helps. John
