Who makes the best electronic ignition conversion kits? It seems like most people use the Pertronix, but I was looking at the Accel 2020. Anyone here use it? Accel 2020 is the least expensive from what I have found at $33.00. I was reading a article on another Mustang forum/site, but couldn't finish reading it without a subscription. They were talking about the Pertronix, Crane, and Mallory units. From what I did read, it basically sounded like they thought the Pertronix was overpriced, especially compared to the others. It seems like a lot of people on these forums have trouble with the Pertronix, but that could be because of the larger number of people that use them. What is the general opinion of these all these units? Thanks in advance.
