Really the weirdest thing happened on my 99 GS400 nobody ever rides in the back of my car because it's my commuter. Anyways the back portion of my drivers set literally fell off, don't know how or why? Has this happened to any of your guy's car? I hope my fix isn't drilling screws from the outside in. Thanks in advance for any info.

 

When you looked at it and tried to put it back, what did you noticed was missing/broken?
