yes it works, it is very simple to hook up. Just make sure you keep the points and all the little wrenches you need to change back with you at all times. Many people report excellent results, however I asked the specific question whether or not people were satisfied with the unit, I got 9 responses, 4 of them cited failure and/or dissatisfaction with pertronix. Along with my own personal dissatisfaction with it leads me to believe it is similar to a crap shoot. I took the wrenches out of my glove box and forgot to put them back in and ended up riding the bus.
