No easy way on a 3/4 ton. Nobody makes a kit for them. I beleive that there's a member here that's doing just such a conversion on the front of a 3/4 ton, try doing a search, you should be able to find it. For the rear, about the only thing i could suggest would be to perhaps take a look at the rear disk setup from a '01-'07 Silverado. I beleive that the entire brake caliper bracket and backing plate could be adapted to your axle.
