waggy 44?

getting ready to swap in a waggy 44. The cheapest one I found has vaccum lines going into the dif and an odd shaped dif cover. I'm assuming its the quadrajunk. should I stay away from this axle?
thanks everyone, Chadc

yeah it would be good to stay away from that version of dana 44. Its the vacumm disconect like i used to have in my 83 grand waggy....
