found a early 70's late 60's ford f 660 yes 660 ...it has square tube axles...any idea what these might be and is it worth 2,000$ ??

you can id, and figure out if you can get parts. Seen some at the junk yard before, and they have a differant bolt pattern. So you can do like we did and cut the centers out of the wheels if it has wheels. You might never break the guts,, and the bearings and seals should be able to get with some crosswork.

so i say maybe if it is a 4x4 and they are in good shape and ratio you can use.
