Re: 14 bolt ff drum size
The 13" drums almost touch the inside of the wheels, the 11" you will have a lot of room.
Classicindustries.com was the cheapest I found for the 11" drums, it looks like they are $129.99 each for the 13" for your truck; I don't know what they are anywhere else. edit: Oh never mind it looks like you just need shoes.

Haha that's ok. I think I have the 13" cause they look huge.

Re: 14 bolt ff drum size
If your drum looks like this one than you have 13" brakes.

Re: 14 bolt ff drum size
I ditched my heavy drums for some discs. shaved off about 80lbs and saved a little money over replacing the drums, hardware, wheel cylinder and shoes.

Re: 14 bolt ff drum size
What are you doing for an ebrake MrHino? That doesn't look like a caliper that is capable.
OP, if you have a full floater, then it should be the larger 13" brakes. I believe it's the semi float that has the smaller 11". |

Re: 14 bolt ff drum size
No both 11" and 13" came on the full floaters, and they both came on the semi floaters too. It depended on what braking option the truck had.
