You can use the 4age dizzy with a bosch ignition module (part number - 249-9-222-067-016) and cost around 60 bucks, It does not allow advance tho, The module has 4 terminals:
15' is fed via 12v ignition on.
16' is connected to the - on the coil.
07' goes to the black wire on the dizzy.
03' goes to the red wire on the dizzy.
^^^^I will be more than likely using this system^^^^
It is also rumoured that you can also use the 2T or 2K electronic ignition type dizzy's but they require some modifying including fitment of the 4age distrubutor drive gear, You can then run vac/mech advance.
