The flap on my 70 amx hood is vac. operated but not hooked up Any one know which is the correct place to hook it to and what about vac. brake booster where is it connected? The orig. carb. was replaced with a holly carb (650 maybe)with only one big port on the back side
with a 3/8 hose going to a rubber plug or grommet on the back of the intake

any help would be great
Thanks
