Thank you everybody for my car mirror comments and suggestions. I get it fixed yesterday, $45 plus 1-hour waiting. Actually they just used 5-minute to get it done, and I watched the entire process. Very easy, just use tool remove the broken glass, and glue the new one back. then it is done. The most important thing is the correct size. The glue is the special glue used to glue the mirror (black glue).
Thank you again!
