Scott, You want to make sure those wheel cylinders are for the Type "F"(front), & Type "FR" (rear)brakes, instead of the Twin Action Type used on the 2 ton, & smaller trucks. I know a couple of guys that ordered what they thought was right for these heavier "400" series trucks, & received the wrong cylinders.The rear cylinders on the Type "FR" have a separate anchor block to hold them in place, instead of the cylinder bolting directly to the backing plate.
