Well, apparently the 3rd DIN attachment pictured above in my first post is from a 2000 Accord and is called an "EX Audio Attachment Kit".
It's from http://www.handa-accessories.com/
And apparently the 2001 & 2002 Accord's have a slightly different dashboard style than the 2000's so they couldn't confirm if this would fit my car or not.
Does anybody have any information on this kit fitting an 02 Accord? Thanks!
