g'day lucas, i have an alfetta gtv 2 litre and run a crane cams electronic ignition system, including module and high energy fireball coil. the car already had it fitted when i bought it but i have fitted similar kits to other vehicles and they are very easy. mine never misses a beat and the performance is great. haven't had to touch it since i bought it. you can look up www.cranecams.com.au for your nearest supplier or ring me at work and i can get a price for you. my opinion is this would be an easier option than modifying distributors to suit.
cheerio,
cameron.
