Just looked this up on the parts computer at work.
The dogbone has superseded from 5s4z-6068-ba to 5s4z-6068-bc.
The mount has superseded from 5sz4-6e042-a to 8s4z-6e042-b (or 8s4z-6e042-a if trans is an auto)
The bolt is a w702801-s439.
The new mount should work with the old dogbone, but i stress "should." Hope that helps.
