I know many will think this idea is a sacrilage but it beats using toyota parts. The new JK rubicon has D44s that are larger w/ bigger bearings and pinions than before. They're a little wider and have coil brackets that may be adapted. They also come w/ lockers and 4:10s. The axles are available as a MOPAR part from a dealer for $1400 each. There's said to be a D60 version coming soon from the mil-spec JKs sold in the middleeast. I know the axles are for a Jeep but you proud sensative types could say they're MOPAR axles. Damn , I'm gonna be hated on this board as a Jeep Lover, oh well.
