HFfarms Have 4 HEI distributors made from v-6 GM distributors all are used parts run fine. Learned from my local junk-yard dogs how to find a live one. Take jumper cables for power turn it ..if it sounds like a popcorn popper is good,make it look like what you took out install time it , lot lot better !!! OK to have a spair with you,pick-up coil cable wears out ,so not bad to start with a new one !!
