11" or 13" drums?

Can anybody tell from the pic what size drums are on the axle pictured? They look smallish to me and I'm thinking they are 11". Saw this 14b ff on craigslist but want the larger 13" brakes. Second pic is what I assume is a 13" drum.

I think you are on the right track. My 88' has the 13" drums, and they are identical to your second picture. Relative to the size of the hub, I'd say that makes the top picture 11" drums.

Thanks, I wanted confirmation before letting it go. I haven't seen 11" drums before, even my 14b sf has 13" drums. I figured that shoulder on the drum's outer edge would be the tell that they are the small ones.

The top picture has 11" drums. I had done a 3/4 ton axle swap on a K5 in the early 90's and had a 14 bolt with 11" drums. I think these were only on early square bodies.
