Rockwell or a Marmon/Herrington would be my guess

Re: 72 k60

that old most likely eaton .

try the heavy hauler section .

I just had a thread up on a 1969 c-60 with napco power pak conversion from back then .

most of them I have read up on and the 1 I worked on are 7.20ish ratio gear . with 39" tall tires . and a Rockwell divorced 223 t-case .

so your going to want a matched pair of axles . time to time there on ebay I have seen but getting parts can be a bit hard . and info is almost non existent on the big stuff like these .

Thanks for the help. I decided to install a matched set from aM35A2 deuce and half . Since this is now a 6 door cab.

Re: 72 k60

and you get 6.72:1 gear ratio .

good axles with lots of support for parts or upgrades.

only thing to watch is the top loader design = clearance for the oilpan and other items that might be in the way . that diff center sticks up there.

Re: 72 k60

No such thing as a '72 K/60. It all depends on which conversion was used and then it's a complete steering drive axle, not just a differential. Rockwell 2.5t axles are your best bet for multiple reasons, if you are building one.
