The frame gets notched and it does get pretty narrow toward the back. Yours does look a bit thinner at the narrowest section than both of my first gens do, but not by much. You'll have to grind the tab of the ridetech bracket where it hangs over that narrow section. I dont think its too much to be worried about, but guys that install them for a living will surely see this and advise you.
