85 359 question

hey guys, first post here, well i just bought a 85 359 two weeks ago and am starting to rebuild it, (yes its going to be worked!)

firstly, it has the two piece lug nut (stud pilot) on the front axle, well i want to add floats to the front of it and found a #### good deal on rims and tires, problem is its hub pilot rims, now the company does have an axle from a 92 379 there, if i wanted to change out everything how would you go about it and what can be used on original axle?
only reason i want to use original axle is because it has brand new king pins and some other things done to it.


so what do i need to convert it to work with the new rims?
do brake's change?

any info would be appreciative,


thanks guys


here is what the truck looks like now, it will be changed over in a couple weeks!
also if anyone has any intake corssover tubes (to make it a dual air cleaner setup) let me know, thanks guys
