Liberty Rear Disk Brakes for A-Body

Regarding the liberty swap, I don't like machining the mount that thin but if it's forged it's probably ok. I realize it sees only torsional load, but that's still pretty thin. I have wide offset axles for bbp and fmj rear drums and wonder if I could go thicker on that flange.

The .100 thickness may be ok.
I'm actually more concerned about metal fatiguing by the addition of a machined pocket with the danger of introducing stress risers.
If I do this, I'm going to make sure to use a milling cutter with a radiused corner so there is a radius all the way around the bottom of the pocket.
It's one thing to use proven factory parts but when you start modifying them, all bets are off.
