i did happen to talk to my tech today, he said the only thing i need to get is the pv off the other truck, part #s are the same on the abs, booster and master. stopping is more important than going, thats why i want the disk rear. but yes correctly is the way to go. i do alot of 55mph plus driving and stopping. then repeat for 72 miles each way on country roads. i also carry 500-600 lbs of tools every day in the bed. so stopping is GREAT.
