rear disc upgrade... anything else beside rear stuff ?

[Nacho-RT74]

a friend of mine finally made to mount the ford explorer setup and is working ( without emergency brake setup ), so now what ?

is better change also dist block/prop valve and master cilinder ? or stock one is good enough ?

Charger 73 with original front disc setup and dist block/prop valve..

Maybe change the master cilinder for some with same front/rear pumping relation on all corners ( kinda all 4 drums from earliers ) ?

and what about prop valve ? maybe better change the dist block for a non integrated unit and get rid off the prop valve ?

Hmmm, good question...

On our Barracuda, we have 4 wheel Wilwood discs, non-power. 
I installed the newer Mopar aluminum dual master cyl and adapter that Rick Eherenberg sells, and an MP Brakes adj pushrod and adj proportioning valve. 

Now, that was from the old single chamber master etc.

With your friend's Charger, I would do the exact same thing.  At least plumb in the adj prop valve.
With a drum brake rear-metering valve, it may cause the rears to apply before the fronts, and leave some residual pressure in the lines causing wear.
