I have a 97 F150 XL. As far as I understand, the door panel has clips that hold it to the door, as well as the screw behind the handle and hooking over the window lip. My door panel is very loose along the bottoms and shakes alot because of this. Where would I find a hardware kit to get the clips???

 

If you have an upholstery shop nearby, get some X Mas tree fasteners from them. We all carry an assortment. They're a one time shot so you usually have to replace them each time you pull a panel.
