I need to replace the plug boot and wire on a Sachs 3.2. The "insert" in the old one broke. This style was very hard to get on and off. Any suggestions on where to get a different style replacement that is easier to get on and off. I have 3W's and quadras...guess I could start there??? Would it be possible to use a wire/cap from a lawn mower ??? Need to shield it???

Thanks,
Steve
