Good Evening Everyone

In cleaning up the engine compartment, I came across this broken bracket & could use your help in identifying it. It is on the drivers side wheel well and appears to be stock. It's 3.5" long. My thought was a mount for an alarm siren, but there are no other indications of an alarm on the car.
Thanks in advance.

Directly in front of the MC

From the top of the DS fender

 

That is the mounting bracket for an old aftermarket alarm siren. Toss it.

It originally held something like this.

 

Thanks again Joe.
Looks more like a Tornado siren than a Toronado one.
More holes to plug.

 

 

The device under the rubber boot is a circuit breaker for power options (power window, seat, etc) and is a factory part. The wiring for those body options will be covered in the Fisher Body Manual, not the CSM.

 

Got It- Thank you!!
