Glad you like it. I'd hate to recommend something and have the person not like it. If you decide to step up to the III (with built-in rev limiter) it's a really simple deal - one screw and two wires. You simply replace the module inside the distributer. In your case you'd probably have to replace the coil as well but that's easy too. Easier than adding their external box for sure.
You can see some photos of my car on the "Garage" section on this website. You can get right to mine clicking on the link in my signature line below the messages. I have better engine photos I can send but here you'll see photos of most of the car.
When I was running the Ignitor II I used a coil by Jacobs Electronics but when I swapped over to the III I went with Pertronix's Flame-thrower III coil. It was about $40 I think. Looks just like any other stock type coil but chrome. Very low ohm unit. The I, III & III systems have their own specific matching coils but as I said a Jacob worked on the II. That might have been my dumb luck though. I'd just go with their unit to be safe.
