Heres what im faced with... I need a new power steering box on my 71 K5, I dont know wether I should just get a rebuilt 4x4 box and fix it like that... or should I get a 2wd box and go ahead and go to crossover. how much more will ti cost to go to crossover? I only have a 4" lift right now but plan to go to about 10" suspension eventually. what are your guys' takes on this?????? thanx in adavnce!
