H1R coils

cleaned up all 3 coils, yet all 3 have the same crack in the casing. i sealed the cracks and tested them against each other, seems they are all reading the same so i can assume they are still fine. i have no service spec for them. p/n is 21121-046/045 but that is really all i know.  Also the mysterious "stop unit" seems ok aside from a cracked mounting hole.  if anyone has a kill switch 21158-001 it would be awesome if you could contact me. apierson82@gmail.com
