Had my sons-in-laws lift off the top on my "57 and put it on end on a portable storage device. Rear window fell out. Removed chrome trim, removed rubber gasket, cleaned glass with Windex and a razor blade, cleaned chrome with mineral spirits, cleaned adhesive from chrome grove with Goo Gone. Ordered new gasket from Casco. Can't find adhesive anyplace (Larry's, Concours, NPD, Casco). Will use wrap around cord and a SIL to reinstall. Those of you who have done this, are your rear windows still firmly in place without the adhesive?
