got a 93 single wheel 4 wheel drive would like to make it dually. on the front axle what will i need? adapters or have to change hub

 

call arrowcraft, they build adapters......im lucky enough to have a fab shop near me in florida that will make about anything i want for a decent price so im good to go when i convert my truck over to the 10x7.25 lug pattern to match the rear i will be using......
