This is my first post and there is probably a post that answers this question somewhere but I haven’t found it. Thanks for any directions here! David

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 .

It’s great. It is simple to do and makes the truck drivable. The hard part is finding the donor... it took me a couple years of looking. Mind you I wasn’t looking really hard. The funny thing is I found the donor 4 miles from my house and got there while 1972 C20 truck for $500. I could likely sell it for $1500-2000! https://www.stovebolt.com/techtips/axles/1%20Ton%20Upgrade/ | | |
