You could get the kit like thereverendbill just noted, you probably get better flow that way, the only problem there is finding a place to mount a cone air filter that's not in the way of something or subjected to excessive road dirt, protected from the elements, and still pulling cool air.
If you have the resources, the original air cleaner can be modified to work with the motorcraft carb with a little cutting and welding. Or you can pick up the air cleaner housing from an old ford that is offset to allow enough clearance to the master cylinder, then duct it to the front of the car just like the factory setup.
I think I like the third option the best, it'll give you cool air while protecting the filter from the elements, and it also maintains a factory appearance in case you're subject to a visual emissions inspection. If the inspector sees an aftermarket intake going to a bright shiny carb, they're more likely to take a closer look at the emissions equipment and find out it's not attached or completely missing.
I'm only pointing you away from the aftermarket type setup because of my own experience with them, it was just a bigger hassle than it was worth. If you think you have a way to make it work go for it and show us what you did, it's always interesting to see new approaches to solve a problem.
