Grab handle bolt.
 

96 850 grab handle bolt size? Dropped one in center counsel while replacing head liner. I've given up on finding it. Tried magnet extension , every nook and cranny. emergency break slot ,seat tracks it's gone.

Worst case, pop off one of the other bolts off the "o ****" handles and bring that bolt to the hardware store for another.

You'll find that bolt once it starts rattling and driving you mad. :D or as soon as you pull in the drive way with a new one
