I'm in the process of taking a blown 1993 Bronco 5.0 motor, taking all the fuel injection, accessories, etc, and putting them on a 302 from a 1979 Mustang Pace Car (1978 engine in all reality). The last hitch I've ran into is the distributor gear. I know that they're both made out of different material and need to swap them but the dist. shaft that I'm using from the '93 is larger and the dist. gear on the 78 motor is smaller. What gear do I need so that I can use the 93 distributor (I have to) with the 1978 engine using the 78 cam?
