Quick comment: you can snag a low pinion Dana 44, narrow track though, out of old Wagoneers. There are also old school low pinion driver-drop Dana 60s, before the venerable '78-'79 HP60s. They have weak axleshafts, but I betcha you can throw in 35 spline shafts with a new/used 35 spline 60 carrier. Not positive, but worth a look if you're determined to use a low-pinion for clearance.
