Brake Upgrade Parts Questions.

I'm considering upgrading my master cylinder to the dual reservoir type and I figured while I am at it I might as well add power brakes. I am told that I need the booster parts from any A Body from 63 to 76. I was thinking that the smaller type from 67 to 70 might be the best bet for me to save space. I see that the M/C with booster assemblies are still available at the parts stores are still available, but that still leaves me with finding the correct brackets. Does anyone know if the 71-76 brackets on the larger boosters interchangeable with the earlier one? I won't have to change or alter my pedal assembly for this upgrade, correct? Any input on this is appreciated.
FWIW, I'll be leaving the front drum brakes alone for the time being.
TIA!

I'm surprised there's been no responses yet, I gathered this wasn't an uncommon upgrade. I was just hoping to clear up those few details before I got into it.
