AAM 10.5 in to a dart, worth the hassle?

I'm just curious what Chrysler is using now that you could actually put in an A-body the same way you do a Dana 60. This thread was just to get some info going as I couldn't find anything on AAM 10.5's here and now realize that the reason is they are too big, I thought they were D60 replacements but apparently not so I'm wondering what is.
