Get the ones listed for the 11" brakes. They are very similar to the ones for 10" drums and may even work the same but the width is different:
10" Drum - Shaft Size=1.73", Housing Bore=2.336, Outer Diameter=2.34, Width=0.47in
11" Disc - Shaft Size=1.73", Housing Bore=2.336, Outer Diameter=2.34, Width=0.25in (This matched the size of the old ones I'm replacing in my KH SBP setup)
I got the ones for the 10" drum the first time, I haven't installed them yet so I'm going to swap them out for the disc variety. Even though the drums variety is wider I pieced them together and I think they'll work with discs anyhow.
