Jay at Mustang Depot has a very nice setup for front disc/rear drum. And NPD has the same basic setup for 4 Wheel Disc. I've got 4 wheel disc brakes off a cobra and Power booster with dual reservior.
If you want to see look at the web page in my signature. Very nice brake master setup. Easy install. 1" bore. Not overly sensitive, but will clamp down and stop you very quickly.
Like Jay said. You can get setup this way whether you have standard or clutch. And if you decide to go hydraulic clutch later, it's not a problem.
HTH,
