You will need one from an '85 Mustang with a 5-speed and a 4 Bbl. Ask for the one with a steel gear. Autozone can get them for $50. Also, you will need the matching ign. box (about $14), unless you are going to use an MSD box.
you don't have to fabricate one. all you have to do is find an older fox-body stang (one that was carbed) and pull the pick-up out of the tank. you might even be able to buy one new from ford or somewhere else maybe.
