What Servo/Master Cylinder is the best to use on..

[justdubbin]

on a type II with Porsche Big REDS

I know a few of you think it's overkill to use Big REDS but I plan on putting a 3.6 six pot motor in my bus so I want to make sure there is enough braking power.

I've found a 964 servo + master cylinder on e-bay (picture below)
I've tried to work out in my head how best to mount it,
if I remove the bit in the Red circle should I mount it facing the back of the bus so I can make up a rod from the brake peddle or keep the bit in the Red circle so the servo faces forward ????



And what about the vacumm hose, will I lose any vacumm pressure because of the hose length? what type of hose do I use? Questions, Questions.....
