Hi James , if you got a ATE servo than you can take the master cilinder 23,8mm from an granada mk2 2,8i and think from a diesel.

20mm will work fine. Have two Capri's running it with Princess 4 pots.

Also have a Capri 3.0 with the 22mm ( 2.8i bmc ) running the Princess 4 pots, also fine. 

Did try it with the 24mm ( Capri Laser servo ) and it was rubbish so don't go oversize.

( All servo assisted )

 

The smaller the BMC the more pressure it gives ( and more assistance ) The bigger the BMC the more fluid it travels, but less pressure and more muscle it needs to push the pedal.
