Here is a picture of the big wire coil pack kit that I have. This is a spare left over from my Duster build. I'll shoot you a PM with the details. You could probably mount the coils to the bottom of the air cleaner housing but you would need to add some reinforcement. The coils are heavy when you add all 8 together. You would also want to put connectors on the power and ground lines so the whole assembly could be disconnected and lifted off the engine.
