They are 6 1/2 inch in the front door panels. If its an extended cab the rears are 4 x 6 inch. Let me tell you from experience replacing the rear speakers in a 97 extended cab is a pain, but can be done. Be cafeful not to break the panel clips then your panels will vibrate when the speakers are turned up.
