I am wanting to install A/F Gauge in my 78, I have the side mount headers and side piped installed. There will need to be a bung placed on the exhaust for the gauge. With the collectors being on the outside of the car where to place the bung for the O2 sensor? Has anyone done this?
How about the 82 models, they require the bung for the O2 sensor. Anyone running the side mount headers on this model, where did you place the O2 sensor?

Thanks

This is where I welded in my O2 bung. I welded it in before mounting the headers and should have put it up a bit higher.
My headers are out at the moment so I plan on welding another bung up and back a bit.
