Orientation of drum brake adjuster bar

The length of the anchor pin will depend on the width of the shoes, and on the offset of the backing plate. Not certain about trucks, but from sedan to wagon, the backing plates are different on vehicles because the wagons would have wider shoes on the rear brakes, generally the same as the front brakes. I'm talking about '60s in general, with all 4 wheels as drum brakes.
