Need help with a fitting on a Holley 2 Bbl carb, please.

On American ‘71 ChryCo cars, carb bowl vent went to a three nipple breather on the passenger side valve cover.
That would make sense, based on the angle of this fitting, as I think the US cars had a front-mounted (?) "opening" in the valve cover.

Don't know if I can make that work on this car though, as the only fitting on the valve cover on that side of the car is the PVC, and it's about 2/3 the way towards the back. Picture I have from when Bazza was starting to tear-out the engine, before he got sick:

I don't think the carb is original to the car, as there's an aftermarket rebuilders tag on it, so that could have something to do with this as well.

Thanks!
