I just changed the ratio of my rear end to 3.55 and had to replace both axles as the splines were chewed.
I looked everywhere and could not replacements or rebuilds.
Finally, after a lot of phone calls I found a used truck shop about an hour and half away who had several to choose from.
I bought two at $100 each they are perfect.
So, I would try the local scrap yards. It worked for me.
