Knock sensor?
 

I need yalls help guys....
today while I was checking out my 1984 c10 (305 carb) I noticed a sensor that’s right next to the starter was broken. I have been looking on line on what the sensor could be.... this is the pictures of it. I really think it’s a knock sensor but I’m not sure. Again it’s in the passenger side near the starter. I ask of yalls help and advice!
