B02A axle shaft fit in B03A axle?

I need to replace a wheel bearing on my B03A and I found a B02A axle near me and was wondering if I can swap in the axle shaft instead of pressing on a new bearing (difficult/expensive). All other specs appear to be the same afaik, besides the gear ratio.
This is what I mean by axle shaft aka the part I wanna switcheroo:

Thank you!

 

Gear ratio shouldn't affect axle shaft. The main differences I can think of to watch for are:

1) Diff type (7.5"/5-lug, 8.0"/factory e-locker, 8.4"/factory open diff)
2) ABS compatibility (all 8.0" 1st gen axles have ABS support even if the truck wasn't equipped with ABS, 8.4" axles may be ABS or non-ABS)
3) Parking brake compatibility (most axles have parking brake cable routed over leaf spring but some have parking brake under)
4) Make sure it's for the correct side!

 

Okay thank you! I'll check all that.
