F-250 front axle conversion kits

I wanted to know if there is a front axle conversion kit to change the front twin traction beam to a solid front axle. I can find the kits for the F-150 and the Bronco but not the F-250. It doesnt make sense why there made for the F-150 but not the F-250. If conversion kits do exist can someone recommend what web sights to refer to? If not has anyone done this conversion and can tell me what might be involved.

i dont know of any kits but i do know if you find a donor f-350 with a solid dana 60 it is a fairly easy swap.
