my door says the truck weighs 7700 and im been trying to figure out what brakes my truck takes. now every f250 i have seen has a rear hub sticking out of the rear axle except mine it is smooth and flat with no hub. i have counted 12 bolts on the diff cover. four bolts on the backing plate for the hubs and 2 u bolts on both sides of the differential cover holding some kind of sway bar. im not sure what i have either part at oreilly auto says with flange or with out flange but im not sure which one it is can you guys give me hand. it says it could either be with 12 x 3 or 12 x 2 1/2 brakes and also my drums dont have tapered holes they are flush with the studs.
