It's a '50 216; I don't have the exact number in front of me, but I talked to the Petronix people and they said I had the right one. Yeah, the magnet fit perfectly. It's 12 volt. With it in, I couldn't even get up to 50 miles/per hour with it floored; with normal points and condenser, I could cruise at 60-65 on the highway (don't have original rear end in it, that's why those speeds). Very disappointing
