    A question that needs to be answered first, is what do you plan to do with your wagon? Are you wanting it to be a trail rig, or an all out off road over lander unit? I personally want my wagon to be capable of going off the beaten path, to explore the local national forests. I want it to be reliable enough to not be worried about putting my daughter in it to drive around, but capable enough to go anywhere. I plan on keeping the Dana 18, but will most likely do some internal upgrades. The axles will see some internal upgrades also, but the housings will remain the same.

    The Dana 44 rear is a good axle in it's own right, with the only real weak spot is the two piece key way rear axle. There are conversion kits that eliminate the two piece to a one piece design.

    Is the width the same as factory wills or will it have to be cut.

    With only eyeballing, the Wrangler axels look to be the same track width. Wagons run the same axles as the CJs, but the truck version is wider, along with the Wagoneer. The early Broncos may be close to the wagon's dimensions, plus you would get the sought after Ford 9" axle. The bolt pattern for the wheels would be the same also. If the axle is wider, then you could run a wheel with a backspace that would keep you within the wheel wells. More than one way to skin a cat.

    Differential Find

    Lower RPMs than the 5.375.

    Open it up and check it out.

    There can be unpleasant surprises lurking in there!

    3.73 gears will be a good cruising gear set. Great find! Did you get the front axle also?
