61 3500 Brake upgrade

[Okiefromwatonga]

Has anyone ever measured frame widths between all the models? I'm sure there are differences between frame gauge but 1/2,3/4,1 Ton and 1.5 Ton all the same width? I'd like to find out so I can look into the possibility of upgrading the 1961 3500 I'm looking at with a more modern brake system.

What would you want to upgrade to and why

I was actually looking at the possibility of converting converting it to a 4x4 with 1 ton axles under it but have since figured out that 1 ton axles would be too narrow
