You could go to the 'Glass Shop", Ithink they use a "Lock Tite" product, but not sure. Several places sell mirror mount adhesive, auto parts stores, Home Depot, Lowe's, etc. It should work, Like I said I have had success and failure. I would cover the interior with a sheet or light blanket in case you drop or spill the glue ( it is a very small amount). Let us know how it goes.
