T5 Clutch Mc

I have a 65 coupe and im getting ready to install my clutch mc. I had to remove the plug under the brake mc so that i have somewhere to install it. Will it be a good idea to enlarge the hole evenly or can i put it a little higher? I figure that if i move it higher it might affect or interfere with the clutch pedal.

i havent mocked it up yet. So i dont know if i have a bad angle or not. Im just trying to see if i could move the hole a little or if i should center the mc where the plug was.
