brake booster vacuum with sidedraughts help??

[project_1200_ute]

i had a mate of mine hit me up over the weekend hes just chucked a a15 with sidedraught dellortos in his sunny and hes wondering where to run the brakebooster vacume line off as the sidedraught manifold doesnt have a place

my ute keeps things simple and doesnt have brakebooster haha

but i thought this must be a real common problem for us boys to run into when changing nanas supermarket runnabout into racecars

any help would be awesome im guessing it will result in pulling carbs and manifold off to tap a thread and some sort of fitting?

take a look at the number 4 cylendar ive drilled into the manifold and welded a fitting in there not a good pic but best i got..
