I put one in my wife's 66 mustang gt 289 about 8 years ago, it worked great until a few weeks ago. My wife decided to sell the car and moved it to wash and wax. She went to start it to put it away and turn over but no fire pertronix just died. I just put points and condenser back in and fired right up. If she planned on keeping the car I would put another one in it just carry points and condenser with me. Things fail some times but I would buy again.
