i would hold out for a dana44, you would be making a upgrade with the dana30..but not much. i would just hold that money toward a dana44. think i saw one on KSL i know there is a EB frame with axles and supposedly a 5.5'' lift (looks like a 2.5'' to me) but its $500 with the dana44 and 9inch
your going to need stock bronco radius arms,(maybe the stock EB brackets cus the EB radius arms are longer then the stock broncoII arms),track bar,make a track bar bracket on the frame,brake lines,front drive line,shocks i think, different front rims,
not sure on the steering. i made a full size bronco steering set up work with a scout box and a EB pitman arm, cant see it being any harder then that. and it was easy.
