Has anyone done a rear axle swap on a C50? From what I've seen in forum comments, swapping rear axles between different medium duty models/trucks is fairly straightforward with the exception of moving spring pads and shock mounts. Is overall width pretty standard on these bigger trucks?

I'm hoping I could find a C4500-C6500 or something similar with gear ratio near 4.10 - 4.56 and disc brakes.

Since mine is already a two speed, I'd love to find another one. Seems like the Dana 19060T might be a nice option but I'm not sure if they come in two speed?

Pictures to come.. wave
