Some of the hardcore 4x4 crowd have found you can install a GM 14 bolt carrier into a Eaton Drop center rear axle. (with a little clearance work) They claim it is such a marriage a bit stronger in because of the Eaton's one piece construction design and has a little better ground clearance than a 14 bolt and a little lighter. All Positives in a stump-jumper, but for your application that swap would open a whole wide rage of carrier and gear options to make that big 'ol AD fly
