wheel and tire question

i have a set of weld draglites 15x10 with a 5.5 back spacing and a set of 28x12.5x15 m/t street drag tires will they fit ?
what do i have to do to get them to.could i get away with just using the mp offset spring hangers and off set shackels or is there more to it than that.
72 duster soon to be 416
thanks you guys and gals you have been alot of help.
