convert a 1971 c30 dually into a srw front

[1971c-30]

ive got a 71 c30 and am wanting to replace the dually front end with a single rear wheel front end ... make sence ? basically ive got some nice 8 lug wheels id like to put on the truck but they are singles not offset duals.. i all ready swapped out rear ends but not sure what i need for the front... can i get some 3/4 ton front hubs off something and swap them off mine... use my spindles and a 3/4 hub ? any info would be a great help... worst case i go to the junkyard and start pulling what i can find...but dont really want to spend the time and waste the money on stuff that isnt going to work.....
