I promised I would be nice here.............
Before I chose my rear axle I looked for about 6 months, searching everyone's list of axles, WMS to WMS of 60", every make and model of any year. '77 Lincoln Versailles, IIRC, was the one that I could pin down. 9" Ford with 60" WMS and 5 on 4.5 -- Other than a factory AMC/Chrysler axle. Every thing else was too wide, too narrow, or off on bolt pattern.
I've been looking for better than 7 years now at MJs XJs, the only rear axles I've seen are- AMC20, D35, D44, 8.25s that would have been factory.
No, I don't care who you are, how much money you have, automakers do NOT make one-offs.
I photo-doc everything.
I've asked you 3 times now to post pics. You post from an Iphone, you have a camera.
Back it up, post pics
