THIS IS A VERY CLEAN LOOKING, AND WORKING FIX. here is what one of our great customers had to say "Great! Thanks for getting 'em out quickly. BTW, those things are great; I don't redo a bike without them any more. Seems like every coil wire I run into is very dry and brittle out where it's been exposed, but is in pretty decent shape back near the coil. Probably because it's not exposed to sunlight and heat back there. I figure ten bucks for the coil wire kit is cheap insurance rather than running on a 40-year-old brittle coil wire. It's just not worth the trouble to NOT do it. ADW" CWsplicerKIT @ BULK COPPER CORE COIL WIRE "7MM" SOLD_PER_FOOT (8337)REMEMBER THIS STUFF IS SOLD PER FOOT !!!!!
