I installed this 6 volt CT70 K0-81 coil today. Item Came fast as always from the folks @ TB. Very Easy installation. Coil mentioned didn't come with instructions however Vince @ tb will guide you thru if you have a problem. I recently installed a rebuilt ct70 motor in a 1974 Z50a. It was a total rebuild body/motor of a 1974 z50a. This coil didn't line up with the original z50a coil position under seat however a quick repositioning/proper grounding and this coil started a motor that hadn't been run in almost 25 years FIRST KICK!!! Thanks Again guys at TB!!! Will be doing more business SOON. Ryan MN
