I was trying to find a picture of what the inside of a cat is supposed to look like. There is nothing inside this one at all, it goes straight through.
I found this link and I did not have the shield that he has under his cat on mine, so maybe someone before me gutted the cat.

i guess I'll get the bolt and studs fixed and see what it does then.
