The edel intake uses 3 studs and on bolt(goes in the bottom right corner if your looking at the opening) to secure it. Also in the instructions you have to drill out the threads from the lower corner of the intake manifold so that you can slide the one bolt through and thread it into the elbow.
I got mine from a Ford dealer, but it was for a 60mm TB. I had to trim mine to make it work for my 70mm TB. If you are just needing one for the stock TB unit, go to your local Ford dealer.
