Cajun,
The guys who know ought to be along soon.
Is there anything wrong with your axle now? Or do you just want to service it?
Bill Marlow has a '46 COE and we have a bunch of other guys who are experts on these things can probably tell you where to find stuff. I found some parts for my '49 2-speed at NAPA. I want to replace seals and bearings next, so answers to your questions should help me, too.
Thanks for using the Stovebolt Page!
John
