No kits out there, but there is a good idea of what you need in the tons o fun forum for a 1 ton dually he gives part numbers.
I'm in the process of doing it to my 51 3600, the rotors he used will fit, I couldn't find a lug stud that would work so just taped the hub to 9/16 18 and will use grade 8 bolts with bushings.
The rotors bolt on the back side of the hub the wheel is on the front side.
The 3/4 ton and 1 ton single wheel are very similar front ends.
