I didn't know about the change in the 3/4-ton axle, but since the question was about going to a 1/2-ton axle I think my answer is still good...

I've only owned one 3/4-ton and its been gone for years. It was a '47. There is a '54 3600 with a Hydra-Matic in my shop today (not mine), and if both where here I could examine the difference.

If I understand the description of the difference it sounds like the spindles would be the same for either one?

Was there a similar change on the 1-tons? I do have a variety of those I could compare.

It's true. I really don't do anything but browse the Internet looking for trouble...
