I drive a snorkeled 76 fj40, but my snorkel is on the drivers side. Sits right in front of the a pillar. Getting something fabbed up is pretty simple, however, I dont know about sticking the straw end into a ford. Carb or FI?
I am planning on using a 93-97 J*%P Grand Scareokee air filter box, looks to fit right in the same spot as the little stock Toy inlet. You can also stick the snorkel hose on it and splice it right into the 2f carb, again I am not sure about your ford. It is waterproof and you can find the filters anywhere, and it was made to move as much as as the 2f engine needs.
Just a thought, let us see what your bootyfab produces!
