Just a standard HT-HZ cap and XE Falcon rotor button. Then you just use standard HT-HZ leads. If you use the Goss replacement HEI coil you can even use the stock HT-HZ coil lead. Goss sell the remade distributors with the small cap and rotor button so you should be able to buy both off them:

You can see the coil in that package but you can but it separately.
Just use the WB-VL plugs and set the gaps for that engine.
Make sure you short the pink and yellow wires at the ignition switch. Have a look on the second page of this thread. Posts are all mixed up now though so you'll have to wing it for the story.
