One more thing, if you do not ha a readily available source for OEM MSD parts, the same pickup is used for mid 70's Fords although the pickup is riveted to a base plate it can easily be removed, wire colorings are the same but the connectors would need to be soldered on from the take out unit. The magnets ARE brittle be careful whether you do the above or use MSD's part. I have both T shirts and felt silly after having worn them
