we had a 3.5 charger 2010 in our shop,, i just happen to walk under it and saw the rear ,, having a spare srt6 rear in the trunk of my car that day i took out my measuring tape the same weight ,,the same length the same mounting bolts, the yoke is smaller than ours but it is the same as the limited i don't know the gearing but that rear will fit into our car,, if you want to post that over there tell them to check it out for themselves,, if i am right the the wavetrac should be cheaper fo us because we just found the wavetrac a new and bigger market. jim
