Why would you want 1? If it isnt well engineered and just pulls hot air out from under the hood all you have done is line someones pocket. And there is probably no one who designs 1 for these old fords. If your heart is set on it design your own and build it with off the shelf parts.
Your best bet will be to buy universal parts and fab up your own.
To avoid hot engine bay temps you need to isolate the filter from the engine bay. You could fabricate a box to mount on the fender well with an opening to the inner fender. Most OEM engines run this way now.
I have seen some hot rods and drag cars run intakes a different way. The ones I saw ran two tubes to the front of the grill and mounted the air cleaner in an empty headlight bucket. It looks clean and rams cold air into the engine. The downside of this is rain would be exposed to the filter.
Another way I have seen it routed is down to behind the bumper. Cold air and mostly out of the rain.
Any way you route it, you'll need a carburetor hat and lots of pipe.
The intake in the picture isn't cold air, so it's not what you're looking for.
These trucks came stock with a cold air intake, however, so if you can pull stock parts from a junk yard, you'll be set for cold air. They had a long duct that went forward and drew air from through the radiator support.
It's pretty easy to add two ducts to those things for increased air flow as well.
Go old school and throw an Offenhauser 2748 carb hat on there with some piping to an inverse conical filter that is through your rad support for a ram air effect.
