I don't know about the sway arm bracket, or the brake lines. I bought this Bronco last October. It was for sale on consignment at a used car dealer. The 4" lift, wheels and tires were on it then. I found receipts for a 4" lift kit and instulation and many other things in the counsole. I did sink $600.00 getting the front suspension right. It needed ball joints and the steering gearbox rebuilt. Eccentric's were installed on the ball joints so that it could be aligned correctly. Money well spent, it drives like new. What I guess I'm saying is that a good (complete) lift kit should include everything you would need to complete the job right. I think mine came from Rough Country. I have Rough Country shocks all around and HATE THEM! It rides like a cement mixer! I just discovered a broken dashboard supporting mount bracked that has broken from the ride. They are going away very soon!
As far as the tires clearing I suppose you need to look at rims designed to fit the Bronco and all should be well there. Time for you to do some internet digging for info I'd say. Good luck, Brian
