Bill - the part I replaced was the inside of the glove box door. It was about $20 and has the part number stamped into it. The little metal spring on that piece fits around a plastic pin that has an indentation on it to keep it in place. If the tip of it is broken off like mine was, that metal spring won't work properly and the door may pop open on its own or it may not open at all. If you didn't know that pin had a tip on it, you would never know something was wrong. It took me awhile to figure out why it didn't work right. Maybe yours is okay.
