Need Help Identifying 4x4 Puzzle truck!

[swamp rat]

My understandig is that both HO-52 and HO-72 could have the load bolt, the main difference was the use of 11" shoes or 13" shoes, the Eaton is kinda a mistery diff, i think the assembly crew had a few too many martinies during lunch breaks. There is a data chart on the forum somwhere that you can compair the number on the eaton case too.

Yes any 14 Bolt conversion adapter plate will work along with the eaton hubs, my 72 has front disk from factory, both the roters and calipers will work for the rear but you won't have an Ebrake unless you use the eldorado calipers.

Use the search feature and type in Eaton disk conversion or other key words and see what you come up with..
