HELP! I have made the 5/16" holes. Some of them only go thru a little bit before I hit somemore solid material. I assume it is metal. Do I drill through that also? I haven't jacked the car up and removed the wheels yet. So I can't tell what I am doing from the top. I want to finish drilling before jacking up the car.

What is the answer?

Thanks
