I converted over to direct fire on my lead ignition using Mallory Hyfire 6AL and two Accel Super Coils also running trailing threw the dizzy. I want to convert my trailing to direct fire. So here's the questions;

*Do I have to run another Hyfire 6AL or can I run a 6?
*Does the box have to be a Mallory or can I run a MSD?

^Your knowledge would be very helpful, Thank You
