Help! I've got the exact same problem with a broken needle and have a replacement needle but don't have the slightest idea how to get in there to fix it. Maybe the answer is to jsut leave it to the pros, but I sure would like to try it myself. Before I get under the dash and screw it up totally, any suggestions, does and don'ts, would be greatly appreciated (other than "don't do what Murdoc did!").
