How do I get a copy of my w2's from the year 2004

See:

Tax Topics - Topic 156 Copy of Your Tax Return – How to Get One

You can also ask for the tax transcript for 2004 from the IRS (1-800-829-1040).

The federal W-2 information WILL be on that transcript.

To get the state info, you need to call the state to get THEIR tax transcript.
