On my 41 1 ton I compared parts list numbers and determined that the front assemblies were the same so I was able to use a 1946 1/2 to disc brake kit that bolted right up.
I had a new rear end narrowed to math the width of the old one with wider brake shoes.
The result is that it cruises at 70mph @ 2000 rpm and then stops on a dime and give me 9 cent change. I could not be happier with it.
