The solenoid? If so, someone sells reproductions but I do not recall who.

T/As had the Challenger emblem in the grille from the factory.

No response to your request for a broadcast sheet decode yet.....

I do not recall ever seeing anyone decode a whole sheet for anyone on here. It takes a lot of time, same reason I do not do it. Call some evening & I can talk you through it so you can do it yourself if you want.
