Yes those can be made to work (bronco), but some of the fronts are 30's, please review my pics I sent you.
However to put them in your jeep will take substantial fab work as the front axle you are buying isn't setup for leaf springs and will have some odd castings in the tubes that need to be dealt with.
By the way gearing and installing any custom axles into your jeep is going to far exceed budget you initially told me you had.
