Bumping this post back to the top for 2008/2009 Hummer H2 owners... a couple OEM console cup holders just popped up on eBay if anyone else wants to do the conversion and add cupholders... https://www.ebay.com/sch/i.html?_nkw=20794348

 

The rear cup holder are a nice addition to the 08 console. What sucks is GM dumped rear air in the 08/09 SUT's when they redesigned the center console for the 08/09,

I believe the SUV delivers the rear air though the headliner which is also different then then SUT.
