The brake parts I showed are for the Bendix style system.One bracket for each side,a left and a right.
I don't know if the Huck system uses them or not.For some reason,I was thinking you are converting to the Bendix type brakes.
Do you have Bendix on the front ?
I don't have any pictures of the Huck style,Denny Graham has a 3/4 ton with Huck style,but it looks different than a 1/2 ton.
Dennys 3/4 ton Maybe a monitor can move all of this to the drive line forum,you would get all kinds of help there.
