Scary
I asked the accessory store at my dealership (large place, good guys I have dealt with for years) and he claims after a phone call or two he has the license plate holder, light, tow hooks and plugs coming. This after I suggested that Hummer sold them like this, so we just need the Hummer parts to restore it the other way... I will know in a few days. Yes, its a brand new 07 block.
For those looking, there is a kit available by Real Wheels as mikejr mentioned. It comes with the chrome hooks and the passenger side hook has an extension to hold the license plate with a light built in and a plug to fill the other hole. Pretty easy fix, but for me I didnt want chrome and didnt want the empty license plate frame.
