I chucked it all and fitted a Scorcher. Just plug and play.
I've also used an early v8 SD1 Lucas electronic (Opus) dissy fitted with a Lumenition module and this worked well. The dissy drops straight in - swap the springs and weights in out of the Disco one if you want to retain the same advance curve.
A cheaper option these days with the higher Aussie dollar may be to get a Buick/Rover MSD dissy complete - comes with adjustable advance curves.
