78 302, say a Fairmont or something. $55 at autozone and $35 for the 'box.

 

Is the wiring available or do you have to pirate it from the junk yard?

 

Pirate it from a junkyard or make your own harness.

 

I got all my Duraspark stuff the the local wrecking yard. Be careful that the control box comes in different colored insulators (where the wires enter the box). Go blue.

Yes get all the wiring from the same yard.

 

Painless makes a harness for this conversion but it's about $100. Also, the 76 Mustang II V8 had, from what I've been told, a more performance oriented curve to it. Not sure if that's accurate or not.

 

I had trouble with the MSD 6AL ignition box in the Fastback this summer (MSD distributor and MSD coil). Rather than do without the car while I decided what to do about the box, I went to the local junk yard and bought a couple of Duraspark control boxes (blue connector and IIRC the number on the box is #12A99); and several associated harnesses (everything less than $30). One box came from an 80s F-150 while the other came from an old 4 cyl Mercury Bobcat. The Duraspark box works just fine with the MSD coil and Distributor (the Duraspark distributor and MSD billet 8579 distributor use the same mag pickup).
