84 5.0 Motor in a 65 Coupe
 

I have a 65 Coupe that I put an 84 5.0 into. My problem is, I don't know what type of ignition system I should go with. I have the distributor from the 84 but I don't have the module. Should I buy a new module and hook it up? What else could I do and what else should I look out for. Please help.
