If you go to their website www.partsamerica.com you will see the many different types for your truck. They had a reference to gross vehicle weight rating, but i would just take and measure the inside of the drum to be sure.

Just measure the backing plate and use good judgement. If the plate is around 11", you have 10" brakes. If it is 12", you have 11" brakes. If it is 14", you have a problem.
