Spring perch spacing on a SRW 14 bolt from 73 to 87 will be 42.5" on center, not sure about the newer models. Stock spacing for 60-72 is 40" on center. Shock mounts will be in the wrong locations too, and one will be facing the rear. Parking brake cable setup will likely be different. Also you may need to change something with the proportioning valve, resresidual vakve or master cylinder for the rear disks; Not sure what you have in there now.
