Vintage Air install with Bulkhead Fitting

[Cramer4918]

Hello everyone! I am in the middle of installing Vintage Air setup in my ‘61 Biscayne. I would like to use a bulkhead fitting at the firewall instead of what Vintage supplies. My question is, what did you all do to connect the air box to the fitting at the firewall under the dash? I don’t plan on hiding it under the fender just so I can work on it if needed without tearing the car apart. It will be a daily driver to an extent, but I would like to clean it up some from what it is supposed to be with the kit. Any info or suggestions would be greatly appreciated.
