Rear Axle Length

Why are you obsessing over this?

Cass gave you a number, I gave you numbers, I know some others have.

With the axle housing flange to flange length 45.25, and using a drum set up, it's going to be 50.55" wide. That's pretty dang close to 50.625... You're roughly 1/16" of from the desired width or, a 1/32ish spacer on each side... That's fricken THIN!

Get the axles at what Cass recommended or what I gave you, either should work fine. 24.96 and 23.58

BTW, you are forgetting the center pin spacing we spoke about the other night. ~1.75". The difference in axle lengths should be equal to the difference in tube lengths or right at 1.375".
