Welcome to stovebolt .
Standard gear ratio for the One Tons would be :
5:14 to 1 with 14 " Drums & 2 & 1/2 " brake shoes .
There are NO aftermarket rear axle kits available .
New parts for this old Eaton axle are scarce to find .
Brake drums are non existent .
Brake parts are hard to find .
Other bolter's will chime in with their ideas
on axle swaps .
