The bumper brackets, Troy. Just like all of us had to deal with.

Well, OK, but most of us who have front anti-sway bars have done just that with zero after effects other than a flatter cornering ride. Notching the bumper brackets is trivial.
@MusbJim has posted great photos of his bumper mount mods as part of this thread:
Print those photos and take them and your bumper brackets to a local welder and they can very easily modify them to notch them for your anti-sway bar and it will never interfere with anything. Ask any local mechanic (like the place where you get your car inspected) for a good local welder - They all know each other. Price range should be anywhere between $50 - $100 for both of them, done.
Mark them as to left, right and top before you remove them so they're oriented the same after the mods, just to be safe.
If you still don't wish to go this route, then you're stuck with what you've got.
