Austin, the guy i spoke with at retrofit, told me he had just finished looking at a 2005/2006 before i called him, was it you abuck99?. If so i got lucky and had impeccable timing. Austin said there is no need to modify the back of the 2007 housing. As bamabrock said, it's as easy as turning on the oven, baking the front lens off, fit the kit, put the lens back on, bake it, and reinstall.
