Same axles as those under the same year Wagoneer, I was told. I've got a couple D44's from a Wagoneer and was told this from the seller. To add, in the latest Off-Road Adventures mag, there is an article on the Wagoneer. Prior to 77, they were narrow tracks (59.2"), wide track was an option?? (65.5"). I haven't measured mine just yet but I won't be using these.
