Good to see you mention this, David, I noticed that particular etypeuk.com sticky recently and made a post about it last week to Jag-lovers asking listers for “expressions of interest” if they would like to see Ray’s mounting hardware kit become a reality.
Here’s the link: EDIS/Megajolt Electronic Ignition System PART II - Expressions of Intereststrong text
The project is gaining momentum and hopefully this will continue with more expressions of interest from listers … enough so to encourage Ray to make this happen. We need to “beat the drums” about this in order to make it happen as I hear this upgrade is one of the best performance mods of all. 
As I recall from reading the UK thread you are one of the lucky ones to have obtained one of Ray’s previous kits. How did that work out for you?

Feel free to post up on the other thread if you’re interested in commenting on Ray’s kit.
Cheers.
