Chances are you're going to have to redo the drain assembly anyway, as the dimentions of the new sink probably won't exactly match that of the one you're removing. Also, the disposal is too heavy to leave hanging on the drain assembly. You're way better off to just take it all apart and put it back together after the new sink is in.
