Gauge Fittings

Alright so heres what i ordered.

Autometer Pyrometer Kit
Autometer Air/Fuel Gauge
Autometer Vac/Boost gauge

Now do i still need to pick up a bung to weld onto the exhaust for the airfuel? I'm pretty sure i do or is this included in the gauge kit?

If anyone has installed any of the gauges listed above, any helpful hints or pictures of your installs would be greatly appreciated, I know the instructions are on gagt.com but any other help would be nice.
