The panel on the bottom of my door (attached to door, above rocker panel), was installed imporperly before I bought the car. It is sticking out just a bit, and I want to install it correctly. What size rivets are used to attach the stupid thing, and is there a better way to get the old rivets out other than drilling them? I drilled one out, but when it was almost out, it started spinning, and it chewed up some of the hole it was in. I dont want to ruin the piece. Thanks.
