There are MANY more advantages to a Waggy 44, such as larger brakes, serviceable bearings, locking hubs, better high-steer options, stronger axle housing, lower gearing options, and more locker options. I run one to match my 'Zu rear. 6-lug wheels are cheap and plentiful.
Sure switching to low pinion is a disadvantage, that's why I'm narrowing two Ford HP44's to run Waggy shafts.
