Convert your socket-style caps to a much stronger caps with HEI-style terminals. Not only do the HEI towers provide a locking connection, but you can hold the wires in place with the supplied retainer. With the retainer in place, there's no way a wire can pop off. The caps fit on a variety of MSD "Pro-Billet" distributors and can be used on many stock GM points style distributors as well.
