Hy again TooMany2count, according to my truck salesman's data book your truck should have 12" front brakes and 14" rear brakes, the maximum diameter on your gauge for the front brakes would be 12.060 and the maximum diameter on your gauge for the rear brakes should be 14.060. The rear brakes may be able to be turned out to 14.090 but I will keep looking for the specification to be sure, hope that helps.
