how to take off electric left front door on 1992 Buick Century

outside handle does not work went to replace the handle and the holes that mount the handle are worn out the replacement handle has compression nuts so they will not stay tight. I can pick up a door for $75 the door look like I will have to take the dash out to get it off. unless someone has another idea to keep the handle tight
