Found missing piece that is held in place by white nylon bushing that goes thru the hole in glass. this 2 piece bushing and metal bracket was laying way in the back bottom of the door. it looks like the plastic piece goes in from the outside and then the second half of the plastic piece pushes inside the outer pc, holding it in place. kind of hard to push in from the outside, no access or working room but with a screwdriver handle against it, I think its in as far as it will go. seems to be holding and there is a little klunk as it moves at first but at least it's going up and down now. Thanks Greg
