Bigunde..Do you know what rear you have in the truck. If it's a Eaton (most likely) you don't have any options other than replacing it. I put a 14 bolt into my K20 but it's a bit easier to swap out because of the leaf springs. I had to cut and reweld the spring perches and the shock mounts. Other than that the driveshaft bolted right up and I had to use the E-cables from the original rear. With the coil spring rear you have to deal with the track arm and its mounting to the rear end. Not all rears have this.
