Door glass channel install help

[skinnan]

Just bought a 72 Chevy truck (common theme around here it appears). Both window regulators were/are bad so I've ordered replacements. Anyways, the metal channel that goes on the bottom of the door glass has fallen off. I bought the flat rubber inserts that go in the channel and around the bottom of the glass (to eliminate vibration I presume). I don't know what kind of adhesive I need to be using to glue the glass back into the channel. Any help would be appreciated. thanks
