I take it you mean the Gen4 frame/style of intimidators; Infamous, Empire II, and Ripper 3?
I can't help you out with the solenoid as I only have the one. But I do have a spare, un-used brass poppet for the Gen4 timmy. It comes with a (very) slightly used rocket cap. Only wear on it is where a socket wrench has made contact with the hexagonal end of the rocket cap.
