Looks good. Just make sure you flip the bottom return spring on your brakes or your self adjusting system will not work. That is a common thing for people unfamiliar with drum brakes to get wrong.
Good eye barnbird. In my experience self adjusting brakes never seem to adjust to my satisfaction. With the spring in that position they have no chance.
