Check your local Auto Zone or Advanced Auto. There is a glue that has two parts. Mix them together and it forms an almost unbreakable bond. It's powerful stuff. Ask the people behind the counter. They will know exactly what you need.
I know what that stuff is, I just can't think of the name of it right now. It has 2 tubes with the stuff in them, one black and one grey, and they work very well.
