actually, i wouldnt
i would sell the rear end, shocks and springs, list them for $100.00 and be happy if i made a connection in the process (a lot would depend on the brakes)
the wheels, i would hold onto until i got the front end redone to match the rear end
(it would be a lot easier to sell a set of four wheels)
oh and once you get that dana bolted in, that "posi" magically turns into a "sure-grip"
