One of the backup lights lenses on our 2001 Navigator came loose due to two of the plastic clips breaking off. The dealer says the only way he can get them is in the whole liscense plate assemby for over $300. No thanks. I guess I'll start watching eBay and checking salvage yards and web sites unless someone can tell where to purchase one. For the moment JB Weld to the rescue.

 

you can use a two part apoxy to fix the clip.
