If you have all the pieces, you may be able to repair it using
J B Cold Weld. It is a two part epoxy and when mixed properly
and applied to an oil free clean surface it sets rapidly
( I use the 'quick' version) and it is sandable and paintable
and can be re-installed in just a couple of hours! It is
available at Home Depot, Lowes and most hardware stores. Costs
about 6 Dollars for the two tubes! Very durable, and easy to
work with! I have used it on a lot of things that otherwise
would have been scrapped!
