I have a set of extra coil packs that were on an 04 6.0L LQ4 engine. The coils have GM part# 12558693 stamped on them. The truck these came off of showed 77K miles on the odometer. The coils are in good shape, with only a little surface rust on the core, they could be cleaned up and painted to look new. One connector is broken where it clips to the bracket, the actual connector is fine(see picture).
