Heehaw, the guy who did this is @HummerH2.org I think you can email him
eric@hummerh2.org. He set up a website to show his Hummer. The site also has forum and things like this site, but ZERO member and ZERO post at forum. He did a good job with several LCD screens, boombox etc, nice but too bad his has those 22" wheels. Contact Eric directly.
i just think it is hard to reach behind the shift column.
