So i have a 1979 Challenger Jet with a 460 ford in it and it still runs on points. I've been looking to switch it to electronic ignition and have searching the web for conversion kits. I've found "electronic conversion kits" from mallory and pertronix but I've also found "points eliminator conversion kits" from ACCEL and Mallory, my question is what's the difference, is there a difference? Which should I go with??
