If you have Harmy’s Despecialized, they’re all available on the MKV, the 77/80/83 mixes in lossless DTS-HD form and the 85/93 mixes in lossy AC3.
Unless you’re specifically looking for the PCM versions, or don’t have Despecialized in MKV (the AVCHDs are all lossy AC3, and I think they don’t include the 85/93 mixes, though I could be wrong about that).
