Rear Drum to Disc Rear End Swap

I just picked up a posi disc rear from a late 70's TA to replace the drum non-posi rear currently in my '81 TA.

What parts do I need to do the swap correctly? I have been told the power brake booster is larger for the disc rears and the proportioning valve may need to be changed.

Any guidance would be appreciated.
