AAM 10.5 in to a dart, worth the hassle?
I've never heard of one being put in... So if your interested in pioneering go for it. With that comes lots of $$$'s and headaches. The housing is larger than a d 60 and I'm not sure on the size of the axle tubes. The full float axle ends will have to be changed, spring perches moved because truck axles sit under the springs and width. This is just the axle itself, one thing leads to another, being a bigger housing you may have to clearance the floor.
Just some food for thought..
