Like I said above after losing a couple redrilled axles (your use may vary) I sent a pair of C-Body axles to Moser to have them cut and resplined (this was in 1980) and used the 11" C-Body brakes and never looked back. Now that there are plenty of ready to use axles I would go this route today.
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
