Either choice of drop shackle or block will work. You will definitely need that c-notch.
I would go the shackle route.
Look at the bed brace directly above the rear shackle.
Some trucks have a 52" leaf spring. Others have a 56" leaf spring.
One of them requires notching that bed floor brace to clear the shackle.
This may help you make up your mind on the chosen method.
