Used once, with a percussion pistol, has served its purpose. The set seems to be universal. I will say between the cost of this kit and the decoupling pulley you are better off if you can find the entire generator for a good price by simply buying it as a whole. I switched and the ALT turned out to be bad anyway so for the first time I was able to save about $70 hours on swapping and replacing parts, plus I now have a new ALT. That's my 10 cents
