That is the biggest reason I switched mine bc the original owner said it was really hard to get it stopped with the 9" brakes so I got on Miss Google and found out 11" backing plates and brakes (I'm thinking they were off a 46 pickup) would bolt right up and I am glad I did it!!!
That's why I was hoping Larrbeard would jump in, I am not sure if has 11" brakes or not.
