I dont know anyone with power brakes on a 230 powered truck....so maybe thats why you get no answer on it...
I would guess the pcv port or the port at the front drivers side of the head would be your choices...these are the only 2 factory ports aren't they? Course you could pick a spot and drill and tap too....would be able to get a position pointing where you want it, pretty close to the booster, away from linkages you wouldnt want to bind with...just an idea....
