Please b careful when pulling instructions off of this forum to install your window motor . I followed my instruction up until it came time to drill out the rivets . Please do not do that for an 87 Grand national . You have to drill holes to get to the three bolts that hold it in . For some this is a no brainer . If my friends was not with me I would have a mess on my hand today . He realized the rivets held the frame and not the motor itself . Also take the radio speaker out it gives you perfect access to everything .Again be careful which instructions you follow . I dont want anyone to make the mistake I almost did
