The most common fixes are:
1. Moving the shock to the outside of the bracket itself, using a longer bolt to literally bolt it to the inside edge. You lose the double-shear strength, but it's a quick fix and most Broncos don't get used hard these days with stiff shocks.
2. Flip the shocks upside down. This works fairly often, as long as the shocks are compatible. Older Ranchos (really old?) used to work just find in a body-up/shaft-down position. Not sure about the newer ones, but I've heard not recommended.
3. Getting smaller bodied shocks. This can work, but it's sketchy sometimes, depending on the brake kit and where exactly your shock mounts were put on at the factory. And which day they were welded!
4. Moving the shock mounts inboard that inch.
I think you'll hear every one of those mentioned in this forum, plus probably a few more. Like moving the shock mounts to the front of the axle, or completely new shock location designs and such. Again, may depend on the brake kit.
If yours has parking brakes that probably puts some more packaging limitations on what you can get away with.
