Found this phone number on Rock Auto wweb site Standard Gear technicians are available to help troubleshoot their parts at 1-866-748-0902. Might be able to help you?

I think it is the same from 1955 to 1964. It looks just like my 57 one. How did you wreck it, just curious. 

Joe, Don reached out to me a day two saying there was a Nfld member looking for one, I am assuming it was you.  I just looked, thought I had a spare set but can't locate them.  I know the axle housing was rusted out but I can't remember what condition the axle retainers were in.  Sorry, but if I do come across them in the next couple of days I will reach out.  I did keep the axles from that housing and could part with them if someone had a need.
