In 60 years there could have been one or more axle swaps too
For example, I wanted to run the readily obtainable 8-lug wheels on my '65 F-350 so I put a 603201-3 ('71-'74) 4.56 axle underneath it. The BOM (usually) tells the real story.Except that I am now in the process of changing the original gears for 4.10. Maybe I'll stamp a "1" after the 603201, or make a tag for the cover bolt!

The Ford 9" in these early years were not limited slip.
Dana 60-2 used the "Power-Lok" locker and was rated for up to 600 horsepower and 600 lb-ft of torque or more. Used in some of the early Chrysler vehicles with the 426 hemi, too.

Not just the Hemi cars, my brother’s ‘70 440 Six-Pack Challanger had a factory Dana 60 in it. I bought a ‘73 IH Travelall for parts years ago and it had a semi floating Dana 60 with the 5 on 5.5” bolt pattern.

I wouldn't exactly call them apples and oranges. More like Fuji and Gala apples. Dana made a semi-floating 44, 60, 60-2, 60-3 and 70 as well as a full-floating 60, 60-3E and 70. They all shared many of the same parts. Here's the drawing for the semi-float axles.

They must have been trying to get rid of some extras then...must be really rare.

Thanks. I looked all over and I could never find any that matched the 602. Is there a link to this page.
