Just and FYI,
Many of you may already know this but I just discovered it. I have been doing some cleaning and organizing of my Jetfire parts stash. I found two of the damper plates I had laying around and noticed that the Jetfire had one specific to that model with OX marked right on it. I never noticed this when I replaced it with a new one. The one for the Jetfire has two spring locations that have are a double spring. Likely for the increased power of the turbo engine.
