Autozone sells a tool to remove the clip behind the crank. I have seen people use a rag and work it back and forth behind the crank, seems like less chance of damage to your panel. Just watch that clip because they always go flying when I do it.
i got my package from crutchfield today. it contained a simple to read and understand break down of the door panel. even crutchfield's diagram had a picture of a guy using a rag to remove the clip behind the crank handle. thanks for the help.
