What advantage does the 58 rear axle offer you?

No advantages, I have a complete 57' that I will be using the entire driveline from for the 49' project.
Being it has less miles...(still need to check condition), I wanted to keep the parts that were together... well together.
Possible different ratio?
Thanks!
