Liberty Rear Disk Brakes for A-Body

It's early, and I ain't too bright to begin with, but...

Couldn't you just install the bracket and backing plate for the liberty stuff on top of the axle bearing retainer, instead of under it, and avoid all the custom machined stuff? As long as the backing plates don't hit the p-brake shoes (which could be omitted for an automatic equipped car not driven by Bo or Luke), the plates would just slide out with the axles any time the axles are removed.

Or, couldn't someone just make a longer adjuster, and banish the bracket-milling business?

Don't bash me, I haven't seen the parts personally; just thinking out loud...
