I have converted to 97/98 coilpack and leads on my classic... started having spark issues at 2.1bar and 665bhp
It is easier to use the 97/98 as it doesn't have an ignitor in but the 99/00 does..
the ignitor on your car is on the drivers inner wing.. if you fit a 97/98 it is just a case of altering the wiring.
