It is a ceramic resister available at any parts store listed for 55 to the early 60's Chevs. You should put a bypass wire on it for quicker starts. If you are useing a selinoid type starter there is a term. on it for that. If you are useing the foot starter you can get a 12 volt one that has a small term. on the side.
