1964 axle swap

[Jmageee902004]

The drive train on my rig is a 64 chevy k10 and the front hubs are shot and replacement ones are not available. So im looking for a newer dana 44 to swap in its place. Not only for the disk brakes but also so i can get parts easier.
Is their a later axle that is about the same length (shorter wouldnt be too big of an issue) that would be a direct swap under my truck? The welder i have isnt good enough to weld on new leaf spring perches. so im hoping thier is an axle with the same perch widths and would just be a simple ubolt swap.
