If the ignition module is gone you have a couple of options
1. Find the original good luck
2. Use 2 X bosch module from an EFI magna use the coils also, mount the modules on a heat sink using heat sink paste if you want them to last. Because you are running two modules you must supply the dizzy signal to both modules.
3. Use a CA20 module and coils form a pintara. The CA20 is a dual spark engine => dual channel module, I am not sure what if any dwell is given between channels.
I have had good luck with option 2 and option 3, I suggest option 2.
Option 2 & 3 you may as well get rid of the knock control computer if you are running one.
