I have some 1.5 and 2.5 ton truck axles that need some bearings. The originals are not made, so I am stuck with cross referencing.

Can anyone help walk me through this so I get the proper cones/races?

For my 1.5 ton truck banjo (Corporation) axle:

Rear wheel outer bearing
GM-144527 Bearing roller, spherical, 2.6252 4.4688 O.D. 0.975 width

also has part number HYD-KD12051Z

Is that enough to find a modern bearing?
