11291 for A/F etc cars, 11290 for B/trucks etc.
The two calipers listed here are structurally the same size. One version has 1.25" dual pistons and the other uses 2" dual pistons.

If you are using these as replacements for the stock caliper with a 2.75" or 2.94" single piston, you want the larger dual piston version from Wilwood.

They all use the same 7.06" floating mount though.

It's possible there is a machining issue with the calipers, but I suspect it's related to the rotor or mounts in this case.
