1970 c10 manual brake/clutch pedal bracket assembly vs. Power brakes auto,

[FoxJ12]

Howdy.
I have a ‘70 C10 1/2 to which originally came with manual brakes and a 3 speed.
I am installing power brakes (disc/drum) and an automatic (4l60e most likely). My question is this:
Are the brake/clutch bracket/ pedal assemblies interchangeable in this scenario? The way I see, I remove the clutch pedal and I can use the stock leftovers for the brake booster, etc.

Thoughts? Comments?

I appreciate the help.
