Contactless distributor trigger?

[Mike Morrin]

I have a friend who is converting an old Jag to run dual fuel LPG/petrol.  

He is intending to fit one of those Jaycar programmable ignition modules,
and some sort of high energy driver.

What he wants is a reliable contactless replacement for his points to fit a
Lucas 6 cyl distributor.  

Any suggestions?

Does anyone know if the Jaycar unit needs to be driven with a square wave,
or can it be driven directly with a reluctor?

regards,

Mike
